Overview of Drain Flies and Life Cycle Basics Drain flies are small moth like insects that frequent damp places in homes and businesses. The life cycle begins with eggs that hatch into larvae and then move through a pupal stage before becoming adults. The legless larvae emerge, measuring 3.5 to 10 millimeters long, with a pale middle and darker ends.
This larval stage is generally the longest, lasting 8 to 24 days, as larvae feed on decaying organic material and microorganisms in their environment. After the larval stage, the drain fly enters the pupal stage, which is relatively brief. Learn about drain fly larva, including what they look like, where they develop, and how to get rid of them quickly and easily.
Identifying drain flies in your home can be crucial, and this article provides insights into their appearance, including larvae and eggs. Known as drain worms, these fly larvae are referred to by several names, including sewer flies, filter flies, and sink flies. Drain fly larvae are difficult to drown because they are able to trap air bubbles and remain submerged for a day or more.
Do not pour insecticides down drains to kill drain flies. In the house, adult drain flies lay their eggs in the gelatinous, sludgy organic material that accumulates on the sides of drains and overflow pipes. Drain fly larvae feed on the decaying organic matter and bacteria that occur there.
The drain fly life cycle progresses through four distinct stages: egg, larva, pupa, and adult. Eggs hatch into larvae, which feed and develop in organic matter, then pupate before emerging as adult flies. about drain flies, including what they look like, where they live, and how to get rid of them.
Drain flies breed in polluted, shallow water or highly moist organic solids. You will find the eggs, larvae and pupae in the muck, slime, or gelatinous film often accumulating on the sides of drains (Figure 3) and condensate pipes for air conditioners (Figure 4), in the sewage filtration tanks, septic tanks and moist compost. Conclusion In conclusion, drain flies do lay eggs, and this process is a critical part of their life cycle.
The female drain fly lays eggs in a moist, protected area, which hatch into larvae after 24-48 hours. The larvae feed on organic matter and develop into pupae, which eventually emerge as adult drain flies.
