Flies

The adult stage of flies is the primary target of pesticide applications to reduce fly populations in and around various animal operations. Generally, these chemical treatments are designed to kill them in resting areas and breezeways used in transit. However, during most of the season, adult flies represent only a small portion of the total fly population. Chemical treatments that focus on the adult flies are noticeably effective; with many dead flies as evidence. However, the results are usually short lived. Because the immature stages of flies are not targeted for control, adult flies emerging from hidden pupae return in abundance. Therefore, what is needed is a system that integrates chemical, cultural, and biological measures. This way, every stage of the fly is targeted, thus maximizing the effect of your fly control program.

Fly Biology

Adult filth flies deposit eggs in organic matter, such as manure and wet feed. This is an excellent food source for maggots that hatch from the eggs. As it goes through its development, each larva eventually transforms to the non-feeding pupal stage. During this time it forms an armor-like coating, which is formed from the larval skin and protects the pupa during its metamorphosis to an adult fly. Upon emergence, the adult fly can then repeat the life cycle.
