Flies can get in anytime someone walks through the door of your business. They can live in drains, thrive on waste and threaten your reputation. Flies visit dumps, sewers, and garbage heaps, feeding on all sorts of moist, decaying matter. House flies are suspected of transmitting at least 65 diseases to humans. Female house flies lay their eggs (usually 75 to 150) in a variety of moist rotting, fermenting organic matter including manure, rotting leaves, garbage, spilled animal feed and soils contaminated with organic waste.

Flies can go through a complete life cycle in as little as 7 days. The adults feed on liquids but can feed on some solids by regurgitated body fluids. They feed on everything from feces to human food and are considered a major health problem.
