Flies are not only a nuisance, they are also some of the filthiest of pests. They are of particular concern for homeowners because their hair, mouth parts, and secretions can transmit parasitic and bacterial diseases, viruses, fungi and other harmful germs. They can also contaminate food.

Flies Found in the Home

There are thousands of different species of flies, but the most common fly problems are caused by those listed below.


The house fly is the most common of all domestic flies. It is also one of the most widely distributed insects, as it is found all over the world. They have gray or black bodies, one pair of wings, and hair-like projections all over their bodies. Female house flies will lay 400โ€“600 eggs in decaying matter or feces, which develop into maggots or larvae. They are attracted to uncovered food and organic waste.


Blow flies are fairly large and usually metallic blue, green, bronze, gray or black in color. They like to breed on decaying carcasses, so significant numbers in a home often indicates an animal may have died somewhere, such as inside a wall or in a crawl space.


Cluster flies are easily recognized by the distinct stripes behind their head. Unlike other flies, they do not lay their eggs in human food, so they do not pose a hazard. Cluster flies will enter the home to take shelter over the winter, often in large numbers. They prefer places that are more removed, such as attics and wall and roof cavities.


Fruit flies are tiny, chunky flies with large red or black eyes. Often seen around food, they are a big pest problem for bars and restaurants. These flies cause a high percentage of the insect contamination of fruit products.


Phorid flies are very small and often mistaken for fruit flies or gnats, but they can be identified because of their humpbacked appearance. They are often seen running quickly across surfaces. They feed on and breed in decaying organic matter, standing water and dead animals and are attracted to slimy drains, sewer leaks and dirty garbage cans.


Moth flies are about 1/10 inch long, gray and heart-shaped. Their bodies and large wings are very hairy. They prefer to breed in polluted waters and wet organic material. The gelatinous material that accumulates in drains is a common breeding ground for them.

Fly Prevention

  • Always cover food โ€“ flies spread diseases by landing on food.
  • Clear away food and liquid spillages immediately.
  • Clean food debris from under kitchen appliances.
  • Make sure all trash bins have tightly sealed lids.
  • Keep compost enclosed and covered.
  • Clean up after pets โ€“ animal droppings are very attractive landing and breeding spots for flies.
