Typical Pest Species: Flies

House flies are one of the most common insects that plague man. They are often a nuisance in residential homes as well as commercial areas. They are the biggest problem in restaurants and commercial kitchens.

Aside from their nuisance factor, house flies carry numerous diseases and germs. They contaminate food by landing on it. They are known to be carriers of typhoid fever, cholera, diarrhea, dysentery, tuberculosis, anthrax, and parasitic worms.

House flies breed in fresh horse manure, garbage, human excretion, cow manure, and rotting vegetable matter. Their larvae are small white maggots which pupate and emerge into flies. Their life cycle under the right conditions is complete in six days with 10-12 generations per summer. To give an idea as to how rapidly flies can propagate, according to entomologist Hodges, “A pair of flies beginning operations in April may be progenitors, if all were to live, of 191,010,000,000,000,000,000, flies by August. Allowing 1/8 of a cubic inch to each fly, this number would cover the earth 47 foot deep.”

Sanitation is, as with many insects, an important part of control. There is not an over abundance of horse manure in our metropolitan city, since the advent of the automobile. There is however tons of garbage. Every restaurant has a dumpster behind the kitchen breeding flies. Every homeowner has an excess of garbage prior to pickup. All are prime breeding sites.

Phorid Flies are usually a problem in mausoleums but they will breed in any decaying organic matter of either plant or animal origin. Thus we have found them in restaurants and bars. Removal of the breeding site, proper sanitation, combined with aerosol or fogging pyrethrums will control the problem. Proper identification and removal should be done by a professional, unless you’re sure which type of fly you’re dealing with.

Often, if you are near a sewage system or stagnant water body you will be infested with these insects.
