Filth flies" such as the house fly can be nuisance pests, but may be potentially harmful to humans and animals. The habits of filth flies favor the spread of bacteria and other disease-causing organisms.
Filth flies often feed and lay eggs on garbage, manure and carrion before contaminating human foods and food preparation surfaces by landing on them.

The filth fly has evolved to live in close assocation with humans. These flies are not only annoying, but are identified with the disease-causing organisms of typhoid, paratyphoid, cholera, bacillary dysentery,infantile diarrhea, pinworm, roundworm,whipworm, hookworm, and tapeworms.
Because these flies have filthy habits are are efficient carriers of diseases. Pathogenic organisms are icked up by filth flies from such places as sewers and garbage and then transferred on their mouth and body parts to human and animal food.

House flies, for example, can spread diseases such as food poisoning and dysentery.

Inspection:

Inspection for House Flies
Inside:
Trash cans-possible breeding sites

Outside-breeding sites:
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.

Most of the time, when you find house flies inside, it is because they are coming inside the structures.
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 buildings.
Rural areas where farms are present may be more problematic for number of breeding sites than areas in a uban setting.
In residential areas, pet manure which is not picked up regularly can be a breeding source for house flies.

Inspecting for Flesh Flies

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. Rendering plants and meat processing facilities may 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. If this is the case, 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 near buildings. 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. Most infestations of flesh flies can be attributed to garbage or rodent carcasses found in or underneath trash dumpsters. Most infestations of indoor Flesh Flies are small in numbers and can be traced to dumpsters, meat processing plants or rendering facilities located nearby. If large numbers of these pests are found indoors, it can usually be attributed to a dead animal such as a rodent or bird. Backtracking the paths of fly maggots will many times help locate the carcass or source of indoor Flesh Fly infestations. If fly maggots are located in light fixtures, an inspection of the attic and nearby wall voids might be necessary.

Inspecting for Blow/Bottle Flies

Blow /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.  Indoors, 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.  Outdoors, inspect the area for dead animals; any nearby dumpsters or 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 peculiar larvae and pupae will be found under or around dumpsters.  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 instar 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.

 

 

Recommended Control and Elimination Measures for Filth Flies

 

1. Exclusion and Sanitation:

• Sanitation is the first measure of defense, even though there are various traps and sprays that are used to kill flies, it is necessary to eliminate the source in order to eliminate them.
• Whenever possible, food and materials on which the flies can lay their eggs must be removed, destroyed, as a breeding medium, or isolated from the egg-laying adult. Killing adult flies will reduce infestation, but elimination of breeding areas is necessary for good management.

• The key to controlling these infestations is to locate and eliminate their breeding sources.

 

• A space spray CB 80 Pyrethrin Aerosol

  (Pyrethrin spray) can be used as a quick kill, reducing populations of flying insects.

• Garbage cans and dumpsters should have tight-fitting lids and be cleaned regularly.

• Drainage will often aid control, getting rid of extra moisture.

• Openings of buildings should be tightly screened with screen.

2. Insecticides : Residual, Aerosols, and Fogging

House flies rest on sunny surfaces in the daytime, and have a tendency to come inside or under eaves at night. These areas where the flies are resting can be sprayed with residual or contact insecticides.
The flies rest on the sprayed surface and pick up enough insecticide to kill them.
When spraying the surfaces, it should be wet enough to the point of runoff, but not enough to form puddles.

Recommended residual Insecticides:

  Cyper WP  is a wettable powder, mixed with water to spray exterior surfaces where flies would land, sprayed once a month. Wettable powders will show up visible on dark surfaces

Use D-Fense SC , if you are concerned about the visiblity on dark surfaces.

Cyper WP or D-Fense SC would work equally well.

Aerosols:
Hand held space sprays for a quick knock down would be pyrethrin contact aerosols:
A space spray CB 80 Pyrethrin Aerosol

(Pyrethrin spray) can be used as a quick kill, reducing populations of flying insects.

  On Time Aerosol

Automatic Dispenser   is an automatic dispenser to be used with the the V Tech Mist Metered Insect Killer.
The On Time Automatic aerosol will last 30 days.

 

Fogging Insecticides-Non Residual

4. Recommended Fly Baits :

Insecticide granule baits such as Bonanza Fly Bait or Maxforce Fly Bait Fly Bait can be used to aid in house-fly control.
The baits should be distributed along walls, window sills or other areas where flies congregate inside buildings, and in areas outside where flies congregate.
Maxforce Fly Spot Bait is a convenient form of Maxforce Fly Bait, where you are may spray in on a surface.
As with all fly control, sanitation is very important when using a fly bait. Remove trash and other breeding sources, so the Fly bait will be there only feeding source.
Make sure the baits are inaccessible to animals or children.
Recommended fly baits would be:
