Drain Flies

What do drain flies look like?

Adult drain flies are a small species of fly; adults grow to be 1/5th to 1/6th of an inch in length.  They range in color from gray to a darker black color. Their body is covered in microscopic fuzz.  Drain flies have large oval shaped wings, but are very poor fliers.  Drain flies can be seen flying erratically and only for very short periods of time.  Drain flies are often referred to as moth flies because of their moth-like appearance.  

Drain fly behaviors

Drain flies will lay their eggs in moist organic matter; and as their name suggests, they are typically found laying their eggs in the build-up found in drains.  Inside homes, adult drain flies can be seen flying around kitchen and bathrooms areas, and they will also inhabit the spaces behind wall voids.  The larvae of drain flies are usually not seen by homeowners, so it is the adults themselves that tip homeowners off to an infestation.

Are drain flies dangerous?

Although drain flies typically live in less than desirable location like drains, sewers, and pipes, they are not known to transmit diseases to people.  Inside homes, drain flies are nuisance pests and can be difficult to eliminate without identifying all of their breeding grounds.
