Termirepel™ Termite Barriers and Termite Films

Various methods of termite control and treatment have been used to control the termite menace.


Chemical Barriers around the perimeter and sub-floor of buildings and other timber structures are used. However these chemicals get accumulated in the soil and volatize producing harmful fumes that are dangerous. Toxic and harmful termiticides that are added to soil can also leach into the ground water causing problems

Steel frames, sand barriers, nematodes have been used to prevent termite damage. Sand barriers with sand of a specific size have been used. However this method has sand barrierslimited effectiveness as termites require only 1/164 inch to pass through a structure.

Metal termite barriers are both expensive and also face problems of rust and corrosion. They are not a feasible option. Also any gap between the metal barriers can allow the termites to pass through.

Termirepel™ Termite Films

Termirepel™added termite barriers and films are a sustainable solution to keep out termites. These films can be used in a variety of applications like construction work, agricultural use, insect repellant wrapping and storage bags for grain and other materials.

In agricultural use termite films have been usedfilms

Termirepel ™ films have been tested extensively at the BAM institute in Germany with favourable results.

In South East Asia, Termirepel™ films have been used to deter weevils from banana plantations. Weevils are large insects that bore in grain and fruit trees.

Termirepel™ films are also being developed for applications to deter bedbugs and cockroaches.

 Termirepel™ Termite Barriers

Termites are estimated to cause structural and construction damage of around 22 billion USD every year. The estimated cost of termite treatment around the world is about 200 million Euros.

termitesIn the construction sector a number of materials are susceptible to termite damage, the foundation and surrounding soil during the construction phase, wooden and synthetic surfaces of the finished project are all vulnerable to attack. Unprotected structures and constructions are susceptible to severe attack from termites and other pests. Termites not only attack wooden structures but also polymeric and other synthetic materials including base frameworks, furnishings and interiors.

Termites are usually detected too late after the damage has been done and treating them after an infestation had occurred is difficult and expensive.

Termirepel™ termite barriers can prevent termite infestation in structures. Termirepel™ is added in a thick film below the foundation. This acts as a termite barrier It prevents the termites form breaching the barrier and attacking any subsequent construction.

Termite barriers are used in a number of countries. Some countries have even made them mandatory in all new constructions to make them termite proof at the source. Termite Barrier Systems are specially developed trenches and plastic coverings to block termites from entering structures.

Termite Barriers are used widely in Europe.  They are plastic films to which Termirepel™ has been added, which are placed below the foundation to deter termites. The termites are repelled by the Termirepel™ in the termite barriers and do not face the problems of conventional termite barriers.

Termite Barriers are useful in preventing termites from entering the basement, footings, the foundation and from accessing any other parts of the structures. They are very effective at preventing termite infestation. Termirepel™ added Termite Barriers have shown good efficiency in dealing with the termite infestation in houses in Europe. They were specially developed with this application in mind.

Termirepel™ Barriers are also being developed for use on roofs of houses to keep away wasps and birds.

The conventionally used termiticides have problems of toxicity and are a danger to non target species. They are also not compatible for the high temperatures of polymer extrusion. They can also be dangerous to the workers processing the sheets to which they are added.

The conventional barriers are not effective at keeping termites away due to the small size of termites.

Termirepel™ added termite barriers are ideal as they are non-toxic, non-hazardous and have a high temperature stability and effectiveness.

Conventional Methods of Termite Control

Termites consume materials made of cellulose. These include wood, wood products, cardboard and paper. untitled1Termites choose their habitat in such a way that they should get a food source & also soil by which they can channel themselves to that food source. They also require warmth & moisture to live. Moisture helps them to form mud tubes. These tubes form a bridge between their tunnels and their food source. The tubes help keep the termites hydrated and offer protection from predators. Termites are not very active in winter but the access to warm areas allows them to feed throughout the cold weather

Signs of Termites

1.      Termites, Dead or Alive

Winged termites are the first sign of termite infestation. New PictureSwarming termites are attracted to light. Worker termites which are small respond quickly by movement when exposed to lights


2. Mud Tubes

New Picture (1)These are made by termites themselves to provide shelter, moisture & warmth under the soil. They have a muddy, flattened appearance like that of a drinking straw. Muds tubes can be seen near cracks, beneath flooring, around baseboards, on pipes, piers, chimneys, behind siding, plumbing and other fixtures

3.      Hollow Wood

While tapping the wood, if there is a hollow sound, it is an indication of termites being present beneath the surface. Dark areas or blisters in wood flooring are an indicator of termite infestation.

Conventional Methods

Barriers: – Barriers are of two types:-

  •  Physical barriers
  •  Chemical barriers

In physical barriers physical resistance of the material can be used to resist termite attack. It can be placed under concrete slabs, foundations & within cavity walls

Metal barriers can be used but it becomes cumbersome & expensive to protect it from termites. This is because termites can enter through cracks as small as .03 of an inch

Chemical barriers as the name suggest uses chemicals to resist the attack which are usually insecticides. Insecticides can be in from of dust.

Active ingredients in dusts include:-New Picture (2)

  • Arsenic trioxide
  • Fipronil

However, these are toxic chemicals, & can leach out in soil & water, polluting the same.

These chemicals are banned in many parts of the world. They have toxic effects to humans as well as environment. Arsenic trioxide can get easily absorbed in digestive system & can cause harmful effects upon inhalation as well as on skin contact. Fipronil is highly toxic to aquatic life & is banned for use.

Termite Baiting is also one of the conventional methods used to control termites. Baiting systems concentrate termites into aNew Picture (3) bait station and then feed the termite bait – a palatable food containing an active ingredient. These active ingredients are chemical & toxic compounds which are harmful to aquatic life, environment as well as humans. Termite baits are designed to suppress or eliminate the termite colony living in the soil.

The disadvantage of this baiting is that:

  • there is no means of coaxing termites in to stations, so it can take ample amount of time before baiting takes place
  • Bait station installations are very expensive & has to be monitored profresionly hence increasing the cost of the system

Natural methods

1. Fungal Pathogens

New Picture (4)Gloeophyllum trabeum is the fungus which repels Nasutitermes exitiosus (Australian subterranean termite).  However curent research has proven that Coptotermes formosanus (Formosan subterranean termite), responds favorably to the presence of G. trabeum and actually seeks out wood that the rot affects.


Steinernematidae, which are termite-controlling New Picture (5)entomopathogenic nematodes, prey on the pests. These small parasites belong to the division of roundworms, invade the host insects and gradually kill them. according to research they do kill off termites but they have only limited repellent function.

Thus these conventional methods which are used have their own drawbacks because of which they can’t be effectively used. An alternative greener & sustainable solution should be adopted to repel termites.
