Filth flies such as the house fly can be nuisance pests, but are also harmful to humans and animals. The habits of filth flies favor the spread of bacteria and other disease-causing organisms.
Filth flies feed often and lay eggs on garbage, manure, and carrion. The flies then contaminate human foods and food preparation surfaces by landing on them.
The filth fly has evolved to live in close association with humans. They are identified with the disease-causing organisms of typhoid, paratyphoid, cholera, bacillary dysentery, infantile diarrhea, pinworm, roundworm, whipworm, hookworm, and tapeworms.
One of the most common filth flies, known as house flies, can cause food poisoning by spreading dysentery.

Inspection and Control Of Filth Flies
Inspection for House Flies
Click Here: House Fly Control
House Flies may be found feeding and breeding in fresh manure, rotting fruits and vegetables, damp garbage, and damp decaying organic materials that are located outside of the structure. When you find house flies inside, check cracks around windows, doors, and vents as possible entry points. It is important to find out where the breeding sources are located and how they are entering the building. Rural areas where farms are present may be more problematic because the number of breeding sites is greater than areas in an urban setting. In residential areas, pet manure, which is not picked up regularly, can be a breeding source for house flies.
Inspecting for Flesh Flies
Control: Flesh Flies usually do not need chemical control. Control is in inspection and sanitation.
Flesh flies generally do not infest structures in large numbers or with any regularity. Flesh flies will be attracted to buildings by odors emitting from the dumpster or the building itself. Animal rendering plants, and meat processing facilities typically attract more flesh flies than other types of facilities such as a hotel or hospital. Occasionally, one or more flesh flies will manage to enter the building. When flesh flies enter the structure, try to determine if a breeding source is located near the building and how flies might be entering the structure. Accumulation of garbage under a dumpster is a common breeding source for flesh flies. Occasionally, a large number of flesh flies will suddenly appear in a particular area inside a building. These flies are most likely breeding inside a dead rodent or bird inside a wall, false ceiling, or the attic.
Occasionally, mature maggots may be found crawling about. These larvae have left the breeding source in search of a place to pupate. If fly maggots are located in light fixtures, an inspection of the attic and nearby wall voids might be necessary. Backtracking the paths of fly maggots will many times help locate the carcass or source of indoor Flesh Fly infestations.
Inspecting for Blow Flies / Bottle Flies

Blow Flies / Bottle flies breed in damp organic material such as garbage and dead animals; therefore, most of these pests found indoors actually originate from an outdoor source. Small numbers of Blow flies in a structure usually point to an outdoor source. If large numbers of these flies are found indoors, it may be a sign of an indoor infestation. Inside, look for signs of dead rodents or birds that may have been living in walls or crawl spaces, or even living in lower cabinets and under major appliances. Outside, inspect the area for dead animals, nearby dumpsters and other garbage containers should be inspected.
Inspecting for Soldier Flies

When Soldier Flies are found in a building, it is usually the direct result of a nearby dumpster or other such garbage receptacle. Inspect dumpsters, compost piles and garbage cans. The younger maggots will be buried in a compost pile or damp organic material and are more difficult to locate. It is during the last stage of the growth cycler that the maggots crawl to visible areas to pupate. The organic material in which the Soldier Fly breeds is always damp and usually in an advanced stage of decomposition.
