House Fly

House Fly – Musca domestica (Linnaeus). Flies have one pair of wings. The house fly has four dark stripes on the top of the thorax between the two wings. They can use a variety of materials for breeding such as animal and human excrement, garbage, decaying vegetable matter and soil contaminated with such material. Having sponging mouthparts, the adults can only ingest liquid materials or solid material which has been liquefied by the regurgitation of digestive juices onto the material which is then ingested as it becomes liquid. Larval stages called maggots are found in almost any warm, moist material that will furnish suitable food for growing larvae.

Blow & Bottle Flies

Blow and Bottle Fly – Family Calliphoridae. Blow flies and bottle flies are closely related and can look very similar to each other except in color. The bottle flies are usually bright metallic green or blue while the blow flies are usually a dark non-metallic color. Both are readily found around garbage dumps, slaughter houses and meat-processing plants. Large black blow flies can be found inside structures where an animal has died, such as a rat or mouse, which is used as a breeding site. Large numbers of these flies may be produced inside by such an occurrence.

Phorid Fly

Phorid Fly – Family Phoridae. Called “humpbacked flies”, Phorid flies are small to minute flies that resemble fruit flies. They are typically found around decaying plant and animal matter. Inside they are associated with plumbing that is leaking and drains in bathrooms and kitchens as well as garbage containers. If sewage is leaking from a pipe and contaminating soil in areas such as a crawlspace or underneath a concrete slab, these flies will breed in the soil that is contaminated with the sewage making them hard to control or eliminate. Sanitation is key to long term control of these flies.
