Drain Flies

What are drain flies?

drain fly illustration

Drain flies are a small fly species with adults growing to be 1/5th to 1/16th of an inch in length. 

They are gray to black; and under magnification, it can be seen that their body is covered in a coating of fuzzy hair.

They have large horizontal wings that are responsible for their short, frantic flight pattern; drain flies are very weak fliers.

When at rest they fold their wings over this body in a distinctive roof-like manner.

Are drain flies dangerous?

Drain flies are not considered to be dangerous; they do not bite and are not known to transmit any human diseases. However, if drain flies are not eliminated from your Middle Tennessee home in a timely manner, their population will grow very large and they will become a huge nuisance within your home.

Why do I have a drain fly problem?

Drain flies are found living and breeding in moist organic debris. Sewers, basements, floor drains, and sink drains are all areas that collect organic debris and allow drain fly populations to flourish. Inside a home that is infested with drain flies, they can be seen flying around drains and resting on the bathroom, kitchen, and basement walls.
