Termites damaging the house foundation

Termites are a group of eusocial insects. Termitestermite damage 2 mostly feed on dead plant material, in the form of wood, leaf litter, soil, or animal dung. All termites eat cellulose in its various forms such as plant fiber. The termites which cause damage to foundation are Dampwood termite, Drywood termite, Formosan termite, subterranean termite. Termites are also known as “silent destroyer”.

termites-in-wood

 

Termites cause $40 billion in damage every year worldwide. Termites can damage a house’s floors just as they can its walls and foundation. When the bugs find food in flooring, the most typical point of attack is actually the structures holding the floor up, not the stuff you walk on every day. The softer woods of floor joists and subfloors are more appealing targets than hardwoods and more plentiful than the backing of laminate or tile floors. By the time they get to the superficial flooring, you can see structural damage in the form of weakened substructures which can be extensive. The type of foundation your house has plays a significant role in how easy it is for termites to tunnel through in search of their food. Earth- to- wood contact provides termites with easy access to food, moisture, and shelter, as well as direct, hidden entry into the building.

Cellulose is the food for termites which is found inIMG_0080+(1) wood. So in most cases of termite damage to foundations is in search of their food as termite can eat 24hours and 7days a week continuously. Most foundation these days are made of concrete and termites don’t eat concrete. Instead, they crush into cracks in the foundation and build a tiny inside tunnels that can threaten our house’s substructure. Concrete-block foundations are less termite-resistant as there is the issue of mortar which has more cracks and is easier to burrow through and weaken. Inside those cracks, they build mud tunnels. These tunnels protect the worker termites as they make way in our home. The termites can slowly widen those tunnels through extensive use, putting pressure on the cracks in the foundation and weakness in the structure itself.

images_3The control measures used are physical barrier which is incorporated during construction, steel mesh and sands of particular sizes, biological control agents. Another protection is chemical treatments, liquid soil applied termiticides, termite baits, building materials impregnated with termiticides. The harmful chemicals generally used in termiticides are Acetamiprid, Bifenthrin, Chlorantruniliprole, Chlorfenapyr, Cyfluthrin, Cypermethrin, Permethrin, Fipronil, Esfenvalerate, and Imidacloprid. These harmful chemicals leach out to the ground and degrade the soil quality as well as not providing the protection to the foundation and additionally these chemicals are carcinogenic. When they are heated, they release harmful gases which can be dangerous for the workers and can lead to harmful diseases.

Termirepel®™is an excellent solution for termites. Termirepel®™ is an anti-termite aversive manufactured by C-Tech Corporation in India. It does not kill termites just keeps them away from the application. It is a non-toxic, non-hazardous and environmental friendly aversive and available in LDPE or EVA forms and it is compatible with all kind of polymers. It has a shelf life of is 25-40 years which varies from application to application.

Termirepel®™ can be incorporated with the foundation to create a termite barrier.

 

Colorado potato beetles at large!!

Haldane discussed the prevalence of stars and beetles in his book “What is life?” published in the 1940s;

“The Creator would appear as endowed with a passion for stars, on the one hand, and for beetles on the other, for the simple reason that there are nearly 300,000 species of beetle known, and _69607665_thinkstock106564984perhaps more, as compared with somewhat less than 9,000 species of birds and a little over 10,000 species of mammals. Beetles are actually more numerous than the species of any other insect order. That kind of thing is characteristic of nature.”

One among the 300,000 species is Colorado potato beetle. An adult beetle is around 10mm long and is orange or yellow with black or brown stripes. The beetle’s main food is potato leaves – a single larva can eat 40 sq cm of leaf per day.

Colorado_potato_beetle_lgThe pretty yellow-and-black-striped Colorado potato beetle is native to wild Solanaceous plants of the semi-arid western United States. Colorado beetles are a serious pest of potatoes.. Both adults and larvae feed on foliage and may skeletonize the crop. . The problem with it began when the beetle broadened its gustatory interests to include cultivated plants in the same family, such as potato, eggplant, and tomato.

Going through the life cycle of the Colorado potato beetle, in late summer, Colorado potato beetles kg26-colorado-potato-beetle-01_lgfly to nearby wooded areas and overwinter beneath bark or other cover. In mid-spring, they emerge and walk until they find potatoes or another suitable host plant. After a little light feeding, mated females lay clusters of orange eggs on leaf undersides. The eggs hatch about two weeks later, and the larvae feed for a couple of weeks before entering their pupal stage. In cool weather the entire life cycle can take 45 days or more, but 30 days is more typical. This means that a second generation can emerge at the perfect time to sabotage midseason potatoes.

Some Growers Say Potato Beetle Becoming Intractable Problem

15.07.2013

Anecdotal evidence suggests the Colorado potato beetle has increased its range in Estonia, and some farmers say the situation is dire, especially as the state declassified the colorful bug as a dangerous pest in 2011.

With potato fields flowering, ETV reported on one Saaremaa island field where the beetle had not been seen before, but which is experiencing a major infestation.

Officially, the farmers are advised to manually pluck the larvae and repeat every day, and only resort to pesticides for larger infestations.

220px-Potato_beetle_larvaeThere are some areas of Saaremaa where the beetle is well-established and can’t apparently be eradicated, farmers said.

Aadu Grepp, one farmer, said that beetles could be found on every fourth or fifth stalk in his fields.

“You have to spray with some toxin at the right time to get rid of it. In a couple days, it will eat a plant, leaving just a stalk.” He said it had been that bad for two or three years. “The bug hatches from the soil and and there’s nothing to do, the only cure is chemicals. There’s so many and it will return in a week or so.”

Grepp sprays his fields several times a year and said some Leisi growers had stopped planting potatoes.

The areas on Saaremaa affected tend to be on the coasts, as the adult beetle gets an assist from the wind. The biggest potato grower on the island, Guido Lindmäe, who has 22 hectares in the interior, says he yet to see a live beetle.

Opinions vary on whether the mainland is worse off. The Crop Research Institute’s Luule Tartlan says it is worse, while the Agricultural Board says that the potato beetle has ceased to be considered a dangerous pest as of 2011.

220px-Kartoffelkaefer_fg01eThe Colorado potato beetle have shifted from its original wild hosts in southwestern North America, it has spread throughout the rest of the continent and has invaded Europe and Asia. Currently its distribution covers approximately 14 million kmaround the world. It has also started appearing in central Asia, western China and Iran. They have started appearing in new regions because of heavy export from the infected area.

Insecticides are currently the main method of beetle control on commercial farms.Colorado potato 78beetle has a legendary ability to develop resistance to a wide range of pesticides used for its control. Plants in the family Solanaceae, which are natural food sources for this insect, have high concentrations of rather toxic glycoalkaloids in their foliage. These toxins protect them from a wide range of herbivores. However, the Colorado potato beetles evolved an ability to overcome toxic defenses of its hosts. Apparently, this ability also allows them to adapt to a wide range of human-made poisons. Also, high beetle fecundity increases the probability that one of the numerous offspring mutates, just as buying 800 lottery tickets increases probability of getting a winning one compared to buying 8 lottery tickets.

Resistance mechanisms in the Colorado potato beetle are highly diverse even within a relatively narrow geographical area. Furthermore, the beetles show cross-resistance to organophosphates and carbamates, and multiple resistance to organophosphates, carbamates, and pyrethroids.

The immune powers of Colorado potato beetle have forced humans to look for solutions above the hazardous insecticides. C Tech Corporation provides a solution Termirepel™ which is very effective, long lasting and Green. The most important unique quality of the product is that it is non-toxic, non-hazardous and environment friendly. Termirepel™helps keep termites, antsand 500 other species at bay and protects the application. They can be incorporated in agricultural films, mulches and irrigation pipes to protect the crops from the vicious pests. The product is available in the form masterbatch as well as liquid solution and is compatible with most the base polymers. The most important quality of the product is that it does not kill the target species but repels them.

Stink bugs!!!!!

Agriculture was the key to development in the rise of976683487_1367746977 moving human civilization. In the developed world, industrial agriculture based on large-scale monoculture has become the dominant system of modern farming, although there is growing support for sustainable agriculture, including permaculture and organic agriculture. But agriculture has to face new challenges everyday in form of pests and insects. One of the problematical insect in agriculture are Stink bug.

bugBugs are present everywhere most of them are destructive in one or other ways. Brown marmorated stink bug (BMSB), or the stink bug, belongs to the family Pentatomidae. They are considered as agricultural pest. Stink bugs are so named because they secrete a foul-smelling liquid that is repulsive to most predators. They are mostly found in Taiwan, Korea, and United State, Asia.

They cause widespread damage to fruit and vegetable crops.download In Japan they mostly damage soybean and fruit crops. In U.S., these bugs feed, beginning in May or early June, on a wide range of fruits, vegetable, and other host plants including peaches, apples, green beans, soybeans, cherries, raspberries and pears.

“The crop damage estimated in USA exceeds $21billion” said United State department of agriculture (USDA).

In Maryland, Pennsylvania, Virginia and West Virginia one of the industries has reported $37million damage in apple growers. Growers in mid-Atlantic region also reported to have worst problems with about 18 percent of crop being ruined.

brown-marmorated-stinkbugMany insecticides are being used to control stink bugs which include chemicals like azadirachtin and pyrethrins (i.e. deltamethrin, cyfluthrin, lambda-cyhalothrin, cypermethrin, sumithrin or tralomethrin) after the approval from EPA as least toxic chemicals to control bugs. But the most noticeable point is that when you spray crops with completely legal and viable insecticides you can kill the stink bug for that instant but the problem is they will be killed that day but after few days you will be faced with  another group of stink bugs which have migrated from outside. They will in turn spoil the quality of food or fruit. So the use of conventional insecticides cannot be a proper solution to this problem.

It being an agricultural application, measures taken to protect food should not contain toxic product by any means as it will be more harmful and lead to many other problems. So the protection should be non-toxic, non-hazardous and eco-friendly.

C Tech Corporation caters to this problem with its niche product Termirepel®™ which is non-toxic, non-hazardous and environmental friendly termite aversive which also repels 500 species of insects. Its life span is 25-40 years depending on the end application. It can be easily incorporated in agricultural tubing and hosing, drip irrigation, agricultural films, tarps, mulches. As it does not leach out from the application it does not contaminate ground water and soil.

Conehead Termites

A rapidly growing species of termite has invaded the U.S. This species, scientific name Nasutitermes corniger, was nicknamed the “Conehead Termite” because of the distinctive cone-shaped head.download (2)

First discovered in Florida in 2001, this highly adaptable termite nests in or on—and happily consumes—trees, shrubs, roots, structures, fences, wooden furniture, scrap wood, paper products and probably many other items made of cellulose. It may build nests on open ground with no trees close by.

This challenging species has tremendous potential for swift dispersal, survival in a variety of structural and natural habitats across a broad geographic range, and decisive economic impacts. There is a sense of urgency to act now to halt and hopefully eradicate this exotic species because if it spreads further and becomes irreversibly established in the United States, it could become a powerful, damaging, expensive, obnoxious, and permanent pest.

tree_termitesOriginally called “tree termites,” they were renamed cone head termites to alleviate the misconception that this pest is only found in trees. Though the species was believed to have been eradicated in the U.S. in 2003, the Florida Department of Agriculture and Consumer Services (DACS) recently confirmed the reemergence of this pest in Broward County, Florida.

Unlike most termites, the conehead termite does not rely on underground tunneling to travel. Instead, they forage on the ground like ants, allowing them to spread quickly. They build dark brown “mud” tubes and freestanding nests on the ground, in trees or in wooden structures. The nests can be up to 3 feet in diameter and have a hard surface of chewed wood.

Conehead termites are an extremely aggressive termite species known for causing widespread property damage in a short period of time. These species need to be controlled to stop this destruction from spreading, or else millions of dollars in damage can be expected. Let’s have a look at the following article.

 

Cone heads invade South Florida

BY DAVID FLESHLER (MCCLATCHY NEWSPAPERS)

Published: December 20, 2012

FORT LAUDERDALE, Fla. – A dangerous Caribbean termite that’s consuming trees, walls and ceilings in Dania Beach, Fla., will be the target of a renewed eradication campaign, with state officials saying this may be their last chance before the species spreads through South Florida.

The Nasutitermes corniger, or cone head termite, whose bizarre behavior includes constructing above-ground nests the size of beach balls and digging visible brown tunnels up the sides of houses, first turned up in Dania Beach in 2001. Agriculture officials thought they eradicated it, but it turned up again last year, and despite the aggressive use of pesticides on nests and feeding tunnels, it keeps showing up.

Pest control professionals, scientists and the Florida Department of Agriculture met in Dania Beach last week to implement a new eradication strategy before the arrival of the spring flight season, when the termites fly off to find new colonies, threatening to spread the range of the wood-eating insects.

“Certainly all of South Florida could be at risk, up into Central Florida,” said Barbara Thorne, professor of entomology at the University of Maryland, who is helping plan the campaign. “Once this gets out, there will be no containing it, ever. So we’re trying to deal with this now.”images

State officials had announced an apparent success against the termite in May, saying they had sprayed 47 sites over a square mile west of Interstate 95 in Dania Beach and found no evidence of live nests. But they also said they would be surveying the area indefinitely, and their surveys found new hotspots spreading out from the area of original infestation.

“We’re still getting activity in the area we treated,” said Steven Dwinell, assistant director of the Florida Department of Agriculture’s Division of Agricultural Environmental Services. “We weren’t as successful as we’d hoped.”

Allen Fugler, executive vice president of the Florida Pest Management Association, which organized the meeting along with the Association of Structural Pest Control Regulatory Officials, said the initial priority will be to come up with a strategy to prevent them from spreading in spring.

“We’re going to look for something as a stopgap before the start of the season,” he said. “Eradication is very difficult.”

The Department of Agriculture is asking the Legislature for $200,000 to hire two full-time workers to seek and destroy termite colonies in Dania Beach. Mr. Dwinell said the initial discussions with pest control professionals suggested the new campaign will involve them more heavily.

This is the worst kind of fear. The fear, of infestation by foreign species in your beloved land.  There has to be some way to surpass this problem. Mankind has come up with creative solutions for each and every roadblock faced by them. So for this particular problem we, at C Tech Corporation have come up with a viable solution.download

Termirepel™ is an aversive for termites and insects. It is non-toxic, non-hazardous and environment friendly repellent which works even against the most aggressive insects.

Combirepel™ is also a non-toxic, non-hazardous and environment friendly product that repels both termites as well as rodents. Combirepel™ WP ( wood protection) is designed as a single eco friendly treatment to treat wood from fungi, rodents, termites and many other insects including Conehead.

These products work on the mechanism of repellence and do not kill the target species, thus keeping in accordance with the need of the hour i.e. sustainability. This green chemistry based wonder product can give even the harshest of termites a run for their home, literally speaking.

 

CROP VANDALIZERS

Nearly 870 million people of the 7.1 billion people in the world, or one in eight, were suffering from Percentage_population_undernourished_world_mapchronic undernourishment as estimated in 2010-2012 by UN. There is a misconception that in most of the countries agriculture as occupation has taken a backseat because of the increased scope in industrialization and technology. Thus there is decrease in the food production and hence undernourishment. But the actual fact is that inspite of the advent of industrialization every nation ensures that the sufficient agricultural land is maintained to feed its population. But still undernourishment is prevalent among the population of the world and reason for it is PESTS.

Nearly 40% of the food production is lost/ damaged on annual basis due to pests. Let’s see some of the deadliest pests who should be made answerable for the rampant undernourishment around the world.

STEM BORER

6953p19 Stem borers are caterpillars that eventually turn into yellow or brown moths.  Larva feeds inside the stem causing drying of the central shoot called dead heart in young plant or drying of the panicle called ‘white ear’ in older plants.  They are like worms that bore into the stems of the growing plant. They sometimes eat the growing point so that the plant does not flower, and they also make the stem weak so that the plant is easily blown over.  In older plants the caterpillars may be found boring into cobs. They imagescan build up from year to year on land used for growing maize or sorghum for many years. They particularly attack late crops.

 Rice, sorghum, finger-millet, maize, pearl-millet, sugarcane, mango, fig, rubber, jackfruit, eucalyptus, mulberry are the crops which are the major victims of the stem borer. They cause nearly 18-40% of damage.

BOLLWORM

Untitled Larva causes drooping and drying of the shoot by boring into it. Later buds, flowers and bolls are damaged and a larva may migrate and attack fresh parts. Heavy shedding of early-formed flower buds due to the pest is common in cotton fields.  Damage by third-generation larvae usually causes the greatest economic loss; however, second-generation bollworms may reach threshold levels. First instars feed on the downloadepidermis of tender plant terminals. Later in stars, however, move into squares, blooms, buds, and bolls. They not only feed superficially but also burrow into young bolls and squares, often hollowing them and facilitating the introduction of pathogens. Each of these larvae is capable of destroying several fruiting forms; therefore, low populations can cause heavy economic damage.
Cotton, chickpea, pigeonpea, tobacco, sunflower, tomato are the most affected crops from bollworms. Bollworms cause nearly 20-90% of loss.

THRIPS

images (5)Thrips are small insects, only about 1/20″, but they can cause a lot of damage. At maturity, they are yellowish or blackish with fringed wings.  Nymphs have a similar shape but lack the wings. Thrips are poor flyers. As a result, damage often occurs in one part of the plant then slowly spreads throughout it. Eggs are laid on or just under the leaf tissues. Both nymphs and adults cut leaf tissues and suck the oozing sap; sometimes even the buds images (6)and flowers are attacked. This results in stunting of the plant, leaf distortion and premature leaf drop. Flowers may be deformed and fail to open properly. Petals may show brown streaks and spots. Their excrement is black and shiny, which may be a clue to their presence.  In addition to this physical rosthrp2damage, thrips also transmit tomato spotted wilt virus and impatiens necrotic spot virus, for which there is no control.

Groundnut, cotton, chillies, roses, grapes, citrus, pomegranate, tea, grapevine, castor, cotton are their favorite targets and causes nearly 25-50% damage in them.

POD SUCKING BUGS

normal_CO_314 Adult pod sucking bug is a dark brown or black is color and is about 30 mm long. Females lay eggs on leaves or on the pods in groups. It takes about 29-34 days to complete the nymph stage and the adult life is of 24-25 days. Nymphs and adults pierce pods and suck up.  normal_CO_317Damaged pods and seeds shrink and become darker.Pulses, safflower, chillies, sorghum, groundnut, tomato, cotton are the major targets of the pod sucking bugs and heavy losses are incurred because them. They have the capability to cause damage upto 50-100%.

ROOTBORER

download (3)Borer larva enters young shoots and tunnels downwards.
Upper portion of the central leaf whorl is thus cut off and dries up leading to dead hearts in shoots from about a month old to 2-3 months’ crop. If the attack is in the early stages the mother shoot dies completely and late attack induces profuse tillering.

prionus-borers10Rootborer are known to attack corn and sugarcane at large. They cause upto 30-45% damage.
Berry Borer and Fruit & shoot borer and Weevil are similar to Rootborer damaging the shoots of the crops. Berry Borer damage coffee upto 30-35% and Fruit and shoot borer damage bringal, tomato, maize, corn, roses etc. upto 15-90%.

MEALYBUG

Mealy bugs are the worst and more common insect that attack cactus and succulents. They leave download (4)on the plant or on the roots in the soil and are capable of very rapidly killing very large specimen. Adults and nymphs suck the sap from plant tissue. This can occur at all stages of crop development. They are about 1-3mm in length and have loose, hairy and waxy cover. They are mobile as adults unlike most other scale insects thus proving that they can easily spread and infect neighbor plants!220px-Formica_fusca_and_mealy_bugs

Infestations cause crinkled and twisted leaves, reduced flower & boll development, smaller bolls, & distorted & stunted plants with a bushy appearance. They are known to damage beans, cashew, cassava, coffee, cocoa, citrus, cotton, groundnut, guava, jute, sugarcane, sweet potato, tomato, apple, apricot. They can cause damage of about 10-20%.

APHIDS
Also known as plant lice, they are diminutive, soft bodied, pear shaped insects which suck sap, download (7)typically during the spring and summer seasons.
Low to moderate numbers of leaf-feeding aphids aren’t usually damaging in gardens or on trees. However, large populations can turn leaves yellow and stunt shoots; aphids can also produce large quantities of a sticky exudate known as honeydew, which often turns black with the growth of a sooty mold fungus. Some aphid species inject a toxin into plants, which causes leaves to curl and further distorts growth. A few species download (6)cause gall formations. Severe infestation results in curling of leaves, stunted growth and gradual drying and death of young plants.

Aphids may transmit viruses from plant to plant on certain vegetable and ornamental plants. Squash, cucumber, pumpkin, melon, bean, potato, lettuce, beet, chard, and bok choy are crops images (10)that often have aphid-transmitted viruses associated with them. The viruses mottle, yellow, or curl leaves and stunt plant growth. Although losses can be great, they are difficult to prevent by controlling aphids, because infection occurs even when aphid numbers are very low; it takes only a few minutes for the aphid to transmit the virus, while it takes a much longer time to kill the aphid with an insecticide.

Wheat, barley, oats, ladyfinger, brinjal, guava, chillies are the common victims of aphids. They cause damage upto 25%.

 Pesticides used since decades have not been successful in protecting the crops/plants from such viciousness of the pests.  Time and again it has been proven that pesticide should become obsolete as solution for protection from pests as use of pesticides has dangerous side effects. Pesticides are toxic, hazardous and pollute the environment. So a solution has to be adopted which have the traits exactly opposite to the deadly pesticides.

C-Tech Corporation provides a solution for the hopeful farmers to protect their crops effectively and efficiently. Termirepel™ a non-toxic, non-hazardous and environment friendly product repels all kinds of insects, termites, pests. They can be incorporated in agricultural films, mulches and irrigation pipes to protect the crops from the vicious pests. The product is available in the form masterbatch as well as liquid solution and is compatible with most the base polymers. The most important quality of the product is that it does not kill the target species but repels them.  Using Termirepel™ will ensure that the crops are protected which gives a ray of hope for the problem of malnourishment.

 

Save history, art, Culture from the pests…

Art, Culture, science and history are the pride of every country and this pride is showcased in imagesheritage buildings known as Museums.  According to The World Museum Community, there are more than 55,000 museums in 202 countries; the ultimate fountain of treasure distributed in over 55,000 buildings. To protect these treasures from the cunning eyes of the thieves’ top security is maintained in most of the museums. Warnings of heaving fines are issued in the museums if damage is caused to an object by anyone. People have to comply with the warnings but such warnings are neglected by the pests. For pests the museum is like a big fat party place with open buffet.

Museum collections are hugely susceptible to pest damage. The cumulative effects of this damage can ultimately destroy a museum object. Therefore, it is important to constantly monitor collections for evidence of pest activity.

Museum pests are biological agents that can cause damage to museum collections. Pests are organisms that interfere with the management objective of the site. Pests come in a variety of forms: insects, rodents, bats, birds and mold. For insects, often the first evidence of their presence is the resultant damage, cast skins, or fecal spots rather than the pest itself.

Insect pests that cause the most damage to museum collections can be arranged into the following groups based on the types of food sources they seek:

1museum - Copy• Textile or Fabrics Pests

• Wood Pests

• Stored Product Pests

• Paper Pests

• General Pests

The nests of mice, rats, birds and bats also affect museum collections because they can attract insects that may then move into collections seeking a food source. What a sight it will be to find these creatures lurking around in the Museum where people expect the surroundings to be safe and hygienic!

The number of pests to be tackled in the museums is so large because of the variety of insects and their number that the authorities get a feeling of waging a war. Let’s go through the following article reported in BCC news on problem of pests in the museums.

Museums waging war on exhibit-eating bugs

Collections of irreplaceable and valuable artefacts in many of Britain’s museums and heritage properties are under threat from a growing army of insects, particularly moth and beetle larvae. Can we stop them munching away on our precious relics?

“If you have ethnographic objects from around the world which were collected maybe 200 years ago, maybe some of these people are no longer producing these objects, maybe some have even died out… you can’t just go and get another one.”

“Bug man” David Pinniger, an entomologist and renowned heritage site pest control consultant, knows how important it is to put an end to an infestation before the damage becomes irreversible.

56 - CopyHe is the person Britain’s biggest museums call when conservators make the terrible discovery that one of the nation’s exhibits has become lunch for some bugs.

He works with all Britain’s national museums, as flourishing populations of a pest called the “clothes moth” have been causing havoc in recent years.

“Virtually all the major museums now have clothes moths, and some serious problems, where 10 years ago we found very few indeed,” he says.

_54802104_theannefanshawedresscmuseumoflondonWebbing clothes moths are about 8mm long and gold-ish in colour, but Mr Pinniger explains that people should not be fooled by their size: “People find big moths and think they do lots of damage, but clothes moths are really small.”

The Pitt Rivers Museum, which is home to Oxford University’s collection of anthropology and world archaeology, was recently forced to call on his services.

Heather Richardson, head of conservation at Pitt Rivers, says: “We have a much higher density of objects on display than a lot of other museums do. In a fine art institution you may have five objects in one case – we have 300 in it.”

The museum has always had a few clothes moths, but in 2005 they took hold of one display case and despite treating the case straight away, the problem spread to other cases.

Ms Richardson says there is a key reason moths love their displays: “These cases are full of natural fibres, hairs and skins – food potentially for beetle and moth larvae.”

Adrian Doyle, collections care conservator at the Museum of London, has to keep a close eye on exhibits he classes as high on the “munchability index”.

“The things most munchable are things probably most valuable, like wool, silk, cotton, older fabrics,” he says.

The museum is home to the Fanshawe dress, which belonged to the Lady Mayoress of the City of London in 1751.

Mr Doyle says: “It is absolutely beautiful and highly munchable – so the risks to that are extreme and we keep a very, very close eye on it indeed.

“We have an enormous costume collection here, and if we had a couple of moths in there I would be extremely worried because they multiply so quickly, and before you know it we’ve got an epidemic on our hands.”

David Pinniger says the nooks and crannies in historic buildings provide perfect hiding places. “To get on top of pests, you need to think like an insect. If you are a clothes moth, you want it dark, undisturbed and nice and warm, and that’s the place you want to be looking.”

So why are the numbers of clothes moths increasing?

78 - CopyMr Pinniger says: “Everyone’s shouting climate change. Because we’ve had a lot of warmer winters, we’re often running our buildings warmer inside now, but there’s also the fact that we have lost some pesticides that were very effective against clothes moths and we can’t use them now.”

Pesticide dichlorvos, which was used in museums to kill insect pests for years, was banned after being found to be carcinogenic.

Val Blyth, the conservator at the Victoria and Albert Museum, says there was a population explosion of webbing clothes moths throughout London three to four years ago, and agrees the loss of chemicals has hampered eradication efforts.

By using moth lures, her team found moths at the V&A were living off debris that fell into a void underneath floorboards in the British Galleries’ wood-panelled rooms.

Adrian Doyle has a theory about why insect numbers are up. “When I was a kid, if you went to a museum and it was cold in winter you wore a coat. Stores were cold in winter, so insects died.”

But pest specialists are also using modern techniques to assess how bad an infestation is and deal with it.

At Pitt Rivers they are trying pheromone traps, using female pheromone to attract males.

Mr Pinniger explains: “There’s a glue board inside which is sticky. The board contains this glue… and a pheromone equivalent to 1,000 female moths, so these poor deluded males are attracted to that [pheromone] and then get stuck in the trap.”

Dee Lauder works for English Heritage Collections Conservation as its collections care manager.

At Dover Castle, a lot of the pests are damp-related. The Kings Hall there is covered in red woollen wall hangings. She says: “The dye that they used for that, carmine, was basically made from crushed insect bodies.

“We’ve laid out realms of protein for the insect pests to feast upon. It’s a steak house.” And in gaps and cracks behind the wall hangings, insects can live without being disturbed.

She is using a moth confusion lure, called Exosex, which coats males moths in a female pheromone muuseum - Copywhen they enter it, ensuring they attract other male moths once they fly back out, interrupting the breeding cycle.

But she says the simplest solution is often the most effective. “It all depends on whether it’s a major infestation. In most cases a lot of it is down to good housekeeping,” she says.

Val Blyth says freezing individual objects at a very cold temperature also kills bugs.

“What I do as a preventive method, or to treat an infestation as we do, is put things wrapped in our chest freezers, and take the temperature down to -30, and over a period of three days this will kill most insect pests.”

When David Pinniger retires, a small group of conservators will continue working to protect Britain’s museums from hungry insects. They plan to discuss their strategies at the Pest Odyssey gathering at the British Museum in October.

The use of Cold treatment to deal with pests when the pests are in such a large number is a very ineffective technique. If hazardous chemical solution is opted then different type of chemicals have to be used for different kinds of pests. In short to protect a huge place like Museums and its jewels from the pests ‘n’ number of methods have to be employed which yields only  feeble results.

Let’s look for a product/method which can deal with all kind of pests single handedly.

Combirepel™, a product of C-Tech Corporation is a one and solution to the problem of pests. It protects the application from rodents, birds as well as insects like termites, ants, paper pest etc. The high point of the product is that it is non-toxic, non-hazardous and environment friendly. The product is in both solid masterbatch form and can be incorporated in polymeric applications. It is also available in liquid and lacquer form which can be coated on any surface to keep the pests at bay.

One should always remember; “Museum’s exceptional heritage is not only an inheritance of the past, reflecting its rich and diverse history, it is also a legacy for future generations and its destruction seriously weakens the foundations of a society.”

The only way to protect the legacy of our future generation is by using Combirepel™.

Evil Weevil damaging crops!!

A weevil is any beetle from the Curculionoidea  superfamily. downloadThey are usually small, less than    6 mm in length and herbivorous. There are over 60,000 species in several families, mostly in the family Curculionoidea . There are more species in this family than in any other beetle group. Scientists estimate that there are over 1,000 species of Curculionidae in North America. Weevils are generally divided into two major divisions, the Orthoceri or primitive weevils, and the Gonatoceri or true weevils. Weevil species occur in a wide range of colors and body shapes. Many are slender or oval-shaped insects. Depending on the species, weevils range in size from about 3 mm to over 10 mm in length. They are usually dark-colored—brownish to black. Some have scales or shiny hairs covering part of their bodies. The most distinctive feature of weevils is the shape of their head. An adult weevil has an elongated head that forms a snout. The mouth is at the end of the snout. Some weevils have a snout that is as long as the body.

images (6)Most of the weevils are destructive to crops and are categorized as agricultural pests. They feed on crops as larvae as well as adults. Most weevils are found in fields, gardens or orchards. They can be very destructive, and their damage is often very expensive. For many years, one of the most destructive weevils was the cotton boll weevil. The black vine weevil, is found in many parts of the United States. It feeds on a variety of plants, including hemlocks and rhododendrons.

A few weevils attack stored grains and seeds. Weevils are often found in dry images (7)foods including nuts and seeds, cereal and grain products, such as pancake mix. In the domestic setting, they are most likely to be observed when a bag of flour is opened. Their presence is often indicated by the granules of the infested item sticking together in strings, as if caught in a cobweb. The most common stored product weevils are the rice weevil, the granary weevil, and the cowpea weevil. Sometimes plant-feeding weevils invade homes for shelter from the weather. Occasionally people accidentally bring seed-feeding weevils into the kitchen.

download (2)Banana weevil is the most important pest of banana plantations. The banana weevil (C. sordidus) is known from virtually all banana-growing countries of the world, including the New World, Afrotropics, Oriental and Australasian regions. According to a study conducted by cirad   banana plots are colonized from already infested neighboring plots or from reservoirs, such as semi-natural wild banana stands. Plot organization within an agricultural landscape thus plays an important role in the spread of weevils, as does the position of the various elements within plots – banana plants, harvest residues, cover crops, pheromone traps, etc. It is its larvae that damage banana plants, by boring galleries in the bulb, which prevent the plant from taking up sufficient nutrients and sometimes cause it to fall.

Substantial losses can result if this pest is not controlled.download (3) Although it will attack all parts of banana suckers and established plants, it prefers decaying banana corm material. Spent stems (cut or left standing), residual corms left after the stem has been cut, underground stubs of corm tissue left after de-suckering, uprooted suckers or stems, and any corm tissues that are large enough to dry slowly are good targets for banana root borer attack. Dispersal within a banana field occurs when adult weevils walk from plant to plant or when infested plants containing eggs and larvae are moved. Dispersal between distant fields undoubtedly is caused by the transportation of infested planting material. Injury is caused by grubs (larvae), which tunnel through the corms. Tunnels which are circular in cross section become wider as the grub grows and are filled with dark-colored debris. Extensive feeding damage by grubs results in root destruction, slowed plant growth, reduced fruit production, and, sometimes, toppled plants. The tunneling by the grubs makes the corms susceptible to invasion by secondary decay organisms. Reduced production and growth of suckers occurs when parent plants are heavily damaged. Affected sucker plants can be recognized by their dull, yellowish-green withered leaves. Relatively little damage is caused by adults feeding on plant tissues.

The damage caused by the banana weevil is demonstrated by this article published recently in The Hindu:

Stem borer a nightmare for banana farmers

B. KOLAPPAN

 The entry of banana weevil, a common pest, in tribal areas across images (2)the Petchiparai dam has become a cause of concern for both farmers and officials of the horticulture department as these areas had once been totally free from the pest.

  ‘Nenthiran’ and red bananas planted in these areas have become its victims. “Commonly known as stem borer, the pest could wreak havoc on banana crop and contribute to drastic decline in banana cultivable area.” said Surendran Joseph, Assistant Director, Horticultural Department in Kanyakumari district, who identified the pests during a field visit.

Mr Joseph said when he received complaints of banana stems bending over and collapsing at Thatchamalai during the flowering stage, he was under the impression it could be due to some fungus attack.

“Even last year there was no incidence of this pest. But now I am surprised to find that it is the handiwork of the stem borer,” he said. Even though the problem was prevalent in Kanyakumari district, particularly in Vilavancode taluk, the borer could not make a foray into tribal areas all these years.

He felt the weevil, which could reach 10-16mm length with a hard-shelled and curved snout, could have invaded the area along with banana suckers brought from outside for planting.

The damage is caused by the grub (larva of the weevil), which makes tunnels as it feeds on the corm and root stock. The tunnels encourage fungal infection, ultimately reducing it into a black mass of rotten tissues. This hinders root initiation and sap flow to the plants.

“The infection will result in yellowing of leaves and withering; particularly, young suckers show symptoms of wilting. In older plants, growth is retarded. In case of severe infection, plants produce small bunches and are easily blown over by wind,” he explained.

Mr Joseph said the pest could be controlled through crop rotation, drip irrigation, selection of healthy planting material and keeping the garden clean from weeds and crop debris. “Uproot the infested plant, chop it into pieces and burn them. Removal of pseudo stem below the ground level,” he said, and advised farmers to avoid planting susceptible varieties such as robusta and red banana

He said if the planting material is suspected of being infested, the suckers should be trimmed on all sides so as to eradicate the presence of eggs and grubs.

The above incident strikes a chord close to home. India being a country majorly dominated by agriculture as a source of livelihood, the crops need to be protected from vicious insects like weevils and bedbugs.

Conventional pesticides used have numerous environmental consequences. The use of toxic pesticides means exposing our pristine soil to the evils of degeneration, degradation of soil quality, ground water pollution, etc. A better way is to use non-conventional products. Unconventional products like Termirepel™ a product of C Tech Corporation are the best for this job. Termirepel™ can be best described as a non-toxic, non-hazardous termite aversive. It is effective against a multitude of other insects and pests like weevils, beetles, etc. It works on the mechanism of repellence and therefore does not kill the target as well as non-target species. Being non-toxic, it does not harm the soil and environment. Termirepel™ can be added to a thin film to protect banana and such crops without contaminating the fruit with pesticides and such residues of harmful chemicals.

 

 

 

 

 

 

Wireworms!!!!

wireworm_boringWireworms are the larvae of click beetle. The larval wireworms are among the most destructive of soils insect pests. Larvae live for 3-4years. The oldest wireworms are the most damaging. They damage potatoes and other crops, including corn, cereals and carrots. Wire worms are attracted to carbon dioxide from germinating seeds and are active in the root zone when the soil temperature is from 55to75o F. They can also weaken or kill emerged seedlings by feeding on tender young roots, boring into the base of corn plants below ground, drilling upward into stalks of larger corn plants.

There are about 800 species of wirewormswireworm_impact1 worldwide. Few of these are serious agricultural threats that cause economic losses. Wireworms are 1-11/4 in length. A female wireworm may lay from 50 to more than 350eggs, 1-6inches deep in moist soil.

Global losses due to insect pests is about 9% which is equivalent to 52 million MT and worth approx $5.7 billion annually. In 1994, losses in potato production in British Columbia were estimated between $500,000 to $800,000. A wireworm-infested field remains infested for three to six years and planting has to be avoided if wireworm levels reach too high a level in the soil.

Many methods are used to control the damage from wireworms. Baits have largely used for controlling wireworms attack random soil sampling since they are less labor-intensive and may detect low wireworm population that soil samples can miss. As, wireworms get attracted towards the carbon dioxide. Baits are most effective when other crops or decaying crop residues are not present to release CO2. There are no effective chemical available for wireworm. Even crop rotation is used to prevent wireworm infected field.

Sometimes wire worms damage stored grain and there is an article from Farmers Guardian which states how wireworms damaged stored grain;

Beware wireworm threat to big bale silage on grass

January 25th 2008

FARMERS storing big bale silage on grassland should be aware of the risk of wireworm attacks, which can reduce the quality and nutritional value of the feed inside.

Silage bales stored on grass rather than hard standing could be at risk of wireworms making their way through the wrap, ruining the forage inside.


The Institute of Grassland and Environmental Research (IGER) said bales it had been storing on grassland had been attacked and farms across the country could be at risk.

Wireworms, the larvae of click beetles, are usually found in permanent pasture. As soil dwellers, they bite through roots and stems at ground level and can attack baled silage stored on the ground. When this happens, 4mm diameter holes will be seen.

Researcher Rhun Fychan said when he opened bales from two different trials IGER was conducting he found up to 10 per cent of the silage surface was mouldy.

At first it was thought the holes in the silage film were due to mechanical damage by the rollers of the bale handler – but closer inspection identified they had been created by wireworms.

With no previous reports of wireworm damage it was possible the attack was a rare occurrence, IGER said. However, farmers storing bales on grassland needed to be aware of the possibility #and were advised to check their bale stacks throughout the winter, assessing the wrap for wireworm damage around the periphery where bales touched the ground.

IGER researchers also said they did not believe wireworm damage would be an issue on hard standing areas. Therefore, if any such problems were identified it was worth considering moving the bales to this type of storage area where possible.

Wireworms are one of the most destructive pests and therefore we should take measures to control wireworm damages.

Termirepel is a non-toxic, non-hazardous and eco-friendly anti-termite/insect aversive which do not kill the termite/insect but repel them from the application. Termirepel can be incorporated in the agricultural film or in the tubing and hosing to protect field from the wireworms.

Dampwood termites- A threat to wood!

Wood is the most frequent and excessively used natural product by man since a very long time. Until this century wood was the single greatest material aid and comfort in every century of our ancestor’s lives! Depending on who starts counting where, the experts all agree that the art and technique of working wood into countless forms of tools, heat, shelter, furniture, transportation, decoration, kitchen utensils, any and every other thing imaginable; and some not, is amazing. The first everything; including the first submarine and airplane; were first made of wood!

The earth contains about one trillion tonnes of wood, which grows at a rate of 10 billion tons per year. Wood finds use in almost all sectors of the industry. It is a vital part of our homes, the place where we rest a tired body. Wood can provide us with a shoulder to lean on in difficult times; it forms the frames of the doors that protect us from outside predators. Words are not enough to stress the importance of wood in our lives!

Although in the recent times wood has had to battle competition from other materials like plastic and its various grades, it has managed to hold its own; lending an old world charm to our surroundings.

Wood has always been vulnerable to attack from insects and pests of all kinds. Termites especially have categorized wood as their all time favorite food.

Dampwood termites known widely and more commonly as “rottenwood” termites given3172184741_614c277e1f their choice of habitat are the largest of all termite species in the world. They range from 1/3 inch to well over 1/2 inches in length. Because of their large size and ability to damage wood more rapidly than their cousins subterranean and drywood termites, they are considered an important economic pest in areas along the Pacific Coast. Soldier and worker dampwood termites can be three times the size of typical subterranean and drywood termites!

Dampwood termite swarmers are generally larger than subterranean and drywood termite swarmers Soldiers are about ¾ inch long with the head and jaws comprising about one third of their length. They have a reddish brown to blackish head and a cream body. Nymphs are about ½ inch long. Dampwood termites are found in areas from Northern California to Oregon, Washington State and in the mountains of Nevada, Idaho and Montana.

usmapdampwoodtermites300They are the largest of all the termite species and they can and will infest homes causing significant damage. These termites differ from subterranean termites in that they form their nests and live inside their food source as opposed to nesting underground. Dampwood termites infest wood with high moisture content. They do not need soil contact in order to sustain themselves, but are commonly found in wood with ground contact. They are commonly found infesting damp or decaying wood, logs, stumps, and dead trees, but will commonly attack structures exposed to moist soil and high humidity.

There are three main species of Dampwood termites, the Nevada Dampwood Termite, the Pacific Dampwood Termite and the Florida Dampwood Termite. The Nevada Dampwood Termite is found in the mountain basins of Nevada, Idaho and Montana. The Pacific Dampwood termite is found from Northern California up to Oregon and parts of Washington State. The Nevada Dampwood termite behaves very similarly to the Pacific Dampwood termite and even lives in many of the same areas.

Neotermes castaneus is the largest dampwood termite, with wings longer than ½ inch, or 15.5download (4)mm. In the southeastern United States it is not an economically important pest and can be found in living trees. N. castaneus swarms during August through early December. Neotermes jouteli infests drier wood compared to other dampwood species. It is known only as an incidental pest in structures with excessive moisture problems. N. jouteli swarms from March to early June, then again in August to early November. Neotermes luykxi is also an incidental pest in structures. N. luykxi swarms from the end of June to early October.

images (1)Finding dampwood termite infestations can be a little tricky because there is little visual external evidence of their presence; they do not produce mud tubes or create visible open holes in the wood. They hide very well in the wood to prevent themselves from drying out, plugging holes with fecal material. Tapping wood that sounds hollow or feels soft is a good sign of a dampwood termite infestation. Different wood will show a different appearance of damage. In sound wood, dampwood termites will eat the softer spring woods, like subterranean termites. In decayed wood, they will form galleries and tunnels that extend across the grain, such as damage by drywood termites. Fecal pellets may also be found in infested structures and will be found stuck to the sides of the galleries, usually forming clumps of feces. However, if conditions are dry, dampwood termite frass will be collected at the bottom of galleries, or outside of the infested material.

The best way of treating a dampwood termite infestation is by avoiding it! This can be effectively achieved by keeping key places moisture free. Because moisture is critical to these termites, solving moisture problems is an important part of dampwood termite control. Other methods of controlling an infestation include several non-chemical methods that have been tried and are available for treatment of localized infestations. The simplest method is wood replacement. If the infestation is known to be localized in a wood element that can be removed and replaced, that should be done. Special attention must be paid while doing the inspection so that all infested material is completely removed and properly discarded, in order to prevent reinfestation.

Heat may be applied to localized infestations, but taking measures that prevent the termites from escaping the treated area into adjacent areas is very important. Cold, especially in the form of liquid nitrogen, can be injected directly into termite galleries in order to freeze the insects. Temperatures around 20°F must be reached so that termites can be killed with very short exposure and precautions must be taken to prevent operator asphyxiation and burns.

Electrocution and the use of microwaves that cause the termites to die by overheating are also used in the elimination of localized infestations. Both methods are limited in penetration and area affected, so thorough applications are needed. In the case of electrocution, copper wires may need to be inserted into the galleries (drill-and-pin applications) in order to reach the termites.

All the methods stated above are not only costly but also not effective. They are not fool proof and are a burden on the pocket!

New methods need to be devised to exterminate this ever- hanging threat to our precious wooden structures. The time has come for going the unconventional way here. We at C Tech Corporation can provide a long lasting and effective solution to combat termite infestations. Our product Termirepel™ is a non-toxic and non- hazardous termite aversive. It is effective against a host of termite species including dampwood termites as also the most aggressive ones. It is available in the form of polymer compatible masterbatches as well as in lacquer form. Termirepel™ is the one and only effective solution to our termite woes!

 

Intruders in our home!!

There is saying in Sanskrit “Attithi Devo Bhav”, meaning the guest at your home is like a God and thus treat him with respect and love.

But what about the unwanted guests who come and stick like leach? They eat, sleep and play in our home and their way of showing gratitude is by destroying our beloved home! Man becomes irksome when any one threatens to destroy his home. One of the most damaging guests to the integrity and the value of our homes are termites. These silent destroyers have now become a huge problem with their capability of bringing the entire house to the ground. Just discovering that we have termites eating our house is enough to cause a great anxiety to us, because it generally is a huge mystery to us as to how these critters get there, and even a bigger problem is how are we going to get rid of them.

images (4)Such guests are our enemies and a war against them is inevitable. The very first strategy of war is to know as much as possible about our enemy and make your plan of action according to it.

Of 2,300 species of termites known to exist in the world, 183 cause structural damage and of those 83 have the record of most economic impact. Less than 20% of economically important species is accounted for by the drywood termites.

cryptotermes_cavifrons01Living up to their names drywood termites live, feed and nest in undecayed wood which has a very low moisture content. Unlike subterranean termites, they do not require any contact with the soil in order to live.

Because of their ability to live in wood without soil contact, drywood termites are frequently carried in infested furniture and other wooden objects into geographical areas where they are not normally found. For this reason, you should be aware of their habits so as to recognize them when they appear.

The wood that drywood termites digest provides moisture needed to survive, thus they do not require free moisture. They are a major wood destroying insect that cost consumers many millions of dollars in damage and control. One estimate suggested Californians spend $250 million dollars a year on this insect.

downloadTheir infestation can be confirmed by inspecting the structural wood in the building. These termites consume both the soft springwood and the harder summerwood of timbers, giving their galleries a smooth sculptured appearance. Drywood termites eat across the wood grain and create chambers, or galleries connected by tunnels. Their gallery and tunnel walls imagesare velvety smooth, and no soil is present. They form many galleries in the wood which are interconnected. If you want to confirm that the infestation is of drywood termites, look for the fecal pellets stored in their gallery which are often kicked out of the crevices. The presence of the fecal pellets also called as frass, accumulated near the structure confirms the drywood termite’s infestation.

fecalpelletsThese characteristics can help distinguish drywood termite damage from that caused by other kinds of termites. For example, subterranean termites usually consume only the springwood, leaving alternating layers of damaged and undamaged wood. The galleries of the subterranean termite also contain soil. Formosan termites consume summerwood, as do drywood termites, but their galleries contain no fecal pellets.

These species are represented by six genera;

  • Neotermes insularis
  • Kalotermes rufinotum Kalotermes banksiae
  • Ceratokalotermes spoliator
  • Glyptotermes tuberculatus
  • Bfiditermes condonensis
  • Cryptotermes primus; Cryptotermes brevis; Cryptotermes domesticus; Cryptotermes dudleyi; Cryptotermes cynocephalus

images (1)These species are found in Australia in the regions of Queensland, New South Wales, Victoria. They are distributed in the coastal region from southern Queenland to Western Australia. In US; Insectitermes minor (Kalotermes) are found in the regions of Florida, Southern California, from the coast of northern California to the coasts of Oregon and Washington, Mexico, Arizona.

Drywood termites have also started appearing in Minnesota, where as per history only subterranean termites were found.

Macro_Termite_SoldierIncreased societal mobility during the latter half of the 20th century has had an enormous impact on the distribution of such pestiferous insects around the globe. The hardwood imported in New Zealand from Australia, has introduced these destructive termites in New Zealand as well. Due to their ability to survive in wood with little moisture content, drywood termites can maintain viable colonies for extended periods and would remain viable during transportation across vast stretches of land and water.

Of these the Insectitermes minor (kalotermes) and Cryptotermers brevis are the most destructive species. Their destruction ability is close that of the Coptotermes acinaciformis; one of thedestructive species of termites.

An Unusual Insect Found in Minnesota: Drywood Termites

University Of Minnesota; November 1, 2012

Jeffrey Hahn, Asst. Extension Entomologist

Termites are present in Minnesota but they are not common. They are found in southern Minnesota up to about the Twin Cities area and very rarely discovered, if ever, in central and northern Minnesota. Minnesota’s native termites are subterranean termites, Reticulitermes spp.

That is why the discovery of winged termites in a home in Minneapolis during September was so interesting and unusual. First, when termites swarm, i.e. winged forms leave the nest en masse, they do so in the spring (and this is very rarely seen in Minnesota). Even more interesting was when the termites were examined more closely, they were identified not as the local subterranean termites but as drywood termites. This group of termites is not native to Minnesota but is most commonly found along the coastal areas of the southern U.S. from North Carolina to California.

The understanding of the species attacking our home is of great importance. The plus point about drywood termites is that their colonies are small and they do not introduce moisture to the wood, as the subterranean termites do. The drywood termites works very slowly, it takes years of their activity to cause appreciable damage and structural weakening to the wood. In contrast to it, let’s say, Formosan termites can literally destroy a home in less than one year.Drywood termite colonies IS02_26develop slowly. The entire colony may take five years or more to mature. Limited space and resources prevent them from even attempting the rapid growth of subterranean colonies. Even with optimal resources, the growth rate of drywood colonies is slow due to their low inherent reproductive rate. Also, in their preferred habitat, water is a precious resource in limited supply at certain times of the year. Drywood termites have several adaptations for conserving as much water as possible. Three pairs of rectal glands compress their feces to remove and retain all water possible before waste excretion. This results in hexagonal fecal pellets (frass). These six-sided pellets, usually found in small piles, are indicative of drywood termite infestation. Drywood termites depend heavily on production of metabolic water.

But, however slowly the drywood termites are working it is not the best thing to happen in the world – your largest financial investment being eaten away by such pest! Thus it might be good idea to keep our eyes and ears open for such house guest and inspect the areas like the attic occasionally. Once the species are found in the house generally exterminators are called as a temporary solution to problem. But in today’s world where everyone is 24*7 busy, the idea of playing hide and seek with such annoying species may not be the viable solution.

C Tech Corporation provides a solution in the form of Termirepel®™ which is very effective and once used does not require any further attention towards the application. The most important unique quality of the product is that it is non-toxic, non-hazardous and environment friendly. Along with termites they even help in keeping ants, mosquitoes and near about 500 insect species at bay. It is available in solution and lacquer form which can be coated on the wood or can be injected in the wood at high pressure. It can be mixed with paints, varnish, etc . to be coated on the application.

The most important feature of this product is that it does not aid to kill the termites and other insects but efficiently repels them. Moreover the product does not leach out from the application coated with it, thus ensuring that the application is protected for a longer duration.
