Fly Identification

Over 30 species of flies belong to the same genus as the house fly and have similar habits. All flies have the following stages of their life cycle:

  1. Egg

  2. Maggot (larvae)

  3. Pupa

  4. Adult​​

Blow Fly

Habitat and Foraging Habits

Eggs are laid singly, but in clusters of about 130; as many as 2,500 eggs are laid in a single month. The eggs will hatch in 10-24 hours depending on the temperature and humidity levels. During periods of rain and warm weather flies can develop from egg to adult in about 10-18 days. Periods of drought or cooler weather normally do not favor their rapid development and breeding. This is why some years their numbers seem to be so much worse than other years.


Flies are a favorite food for BEES! If you are allergic to BEE stings, you'll want to pay close attention to the fly population.


Proper sanitation is a "must" in controlling any type of fly. Regular (at least every 3-4 days) and careful disposal of all manures (pet waste), rotting plants, and other organic materials are extremely important to reducing their breeding places. Remember the majority of flies breed only in moist places rich in organic matter; they do not develop in dry situations. Water-soaked areas around garbage cans are favorite breeding areas. Garbage cans should always have tight-fitting lids. Flies also enjoy hanging out in tall grass and weeds near their favorite breeding areas. You may also see them sunning themselves on buildings as the temperature warms up in the Spring and cools off in the Fall. This is also the time of the year when you are most likely to find them buzzing around inside your home.


Controls, Prevention and Habitat Alteration


  • Dry out or do away with breeding areas.

  • Get rid of all garbage, pet, and animal waste at least twice a week.

  • Use garbage cans with tight-fitting lids.

  • Replace old or damaged screens (use 16-18 mesh screens).

  • Make sure your automatic door closures are set in the right position (summer and winter settings).

  • Caulk all cracks and holes to prevent entry.

  • Keep grass mowed around buildings.

  • Store garbage away from buildings.
