Flies can be spotted all over the world, both in the outside environment and indoors. The prominent areas where flies are found are in close proximity of humans and animals. They are attracted to different filthy surfaces.

Many different types of flies can be found in homes and buildings where humans are present. Unlike the outdoor locations, indoor fly sustenance is gained through decomposing trash and other food waste. Moist, damp foods provide the fly with the nutrition it needs, which is why decaying organic material is the ideal meal. In homes, the temperature tends to speed up the decomposition process, providing the right environment for a fly’s food to spoil, as well as for the insect to thrive. During the day, flies are most active during the hottest hours, as the rate of decomposition  of their food sources speeds up, making the scents more appealing and pungent, and creating an environment ideal for a large fly population. In homes and barns, they can be found near or in ceilings. Wires and beams are typical resting locations for the flies during the nighttime hours.

There are four stages in the life cycle of a fly. They begin as eggs being laid in decaying matter, which hatch to a long, whitish yellow maggot (larvae) stage within 8 to 20 hours. The larvae stage takes between four and thirteen days, but only within optimal temperature range. The third stage is the pupa. During this time, the insect completes the development stage inside its new casing – this time a dark brown color. In between two and six days, the fly will break free into the adult stage and begin the process again.

One of these flies is the Blandford fly. It belongs to the species of black fly; a biting insect. The Blandford fly’s English common name derives from a major outbreak of people being bitten around the town of Blandford Forum in Dorset, England, in the 1960s and 1970s. In a four-week period during the spring of 1972, some 600 people were estimated to have visited their doctors in Blandford to be treated for insect bites.

It was then in 1980, the Dorset County Council asked the Centre for Ecology and Hydrology, formerly known as the Institute for Freshwater Ecology to come up with a solution to keep away the Blandford flies.

Blandford fly spends its larval stage in the in the weed beds of slow flowing rivers and when the fly emerges, the female seeks a blood meal before mating.

Blandford fly bites are usually most common during May and June. The Blandford fly tends to bite least in the early morning and late evening. Bites often occur on the legs and are very painful. They can produce a severe, localized reaction around the area of the bite. Its symptoms include: swelling, blistering, high temperature fever, joint pain.

The Blandford flies are been recorded in the following countries – Czech Republic, Denmark, Finland, France, Latvia, Germany & Austria, Belarus, Belgium, Southern England, Italy, Lithuania, Luxembourg, Netherlands, Norway, Poland, European Russia and Western Siberia, Slovenia, Sweden, Turkey, Ukraine.

Herefordshire bite allergies blamed on Blandford fly

17th May 2011, BBC News, England

Doctors believe the bites may come from the small black insect, which has caused similar problems in Dorset.

Dr Paul Harris from Belmont Health Centre in Hereford said each doctor at the practice is seeing around five cases a week.

“We’ve seen some that can be the size of your palm across and very swollen, red and inflamed,” he said.

He believes the flies were attracted to a water feature in his back garden.

Andrew Thomas, from Lugwardine, Herefordshire, and other members of his family, were badly bitten.

Blandford fly: surge in ‘infected’ insect bites blamed on new super fly.

29th July, 2010, The Telegraph, England

The Blandford fly, a tiny insect normally found in the country, appears to have reproduced in city areas, largely thanks to the growing popularity of garden water features.

Wildlife experts said the tiny insect, can leave bite which often turns infectious and potentially leaving some victims in need of hospital treatment.

They fear the Blandford fly, which measures only about two or three millimeters long, is spreading amid reports of a rise in infected insect bites over the past few weeks.

Experts blamed the recent warm and humid which has made insects, including horseflies, mosquitoes and midges, more active, particularly in the evening.

The balmy summer evenings have also encouraged people into their gardens where they are more likely to be bitten.

Conventional insecticides have proven to be a failed solution to give effective results. These insecticides are toxic in nature. They kill target as well as non target species. They are also hazardous to human health. Moreover, species like Blandford flies are not at all affected by the toxic effects of these insecticides.

C Tech Corporation can offer a solution to overcome the damage caused by Blandford flies. Termirepel™ anti-termite, anti-insect additive is an ideal solution for the prevention and control of flies. It follows 6 pronged strategies which are extremely effective on flies as well as insects like termites, beetles, grasshopper, bugs etc.

Termirepel™ is thermally stable and does not degrade on exposure to heat and sunlight. It does not kill or harm the insect but repels them. It does not volatilize and does not degrade the soil. It is RoHS, RoHS2, REACH compliant and FIFRA exempted.
