Drain Flies Identification Guide

What are drain flies?

The drain fly is a small species of fly and is sometimes confused with small moths because of their appearance. Their body is black or gray, and their wings covered in fuzzy hairs. When at rest, the wings of the drain fly fold over their body in a roof-like manner. In addition to their fuzzy wings, drain flies have an erratic flight pattern, which helps to identify them. Drain flies are weak fliers and are only able to fly short distances.

Are drain flies dangerous?

Drain flies flying and gathering around drains are a big annoyance for either home or business owners. Drain flies don’t pose direct risks to people. The biggest problem with drain flies is they breed quickly and in the right conditions create large populations that are difficult to control. Drain flies that become squished leave behind black powdery marks on walls and other surfaces.

Why do I have a drain fly problem?

Drain flies are attracted to areas of standing water as they like to lay their eggs on the film that builds-up on the top of standing water. Clogged drains, leaky pipes, and other water issues will create areas of standing water and attract drain flies to a property. 

Where will I find drain flies?

Drain flies are most problematic around drains where moist organic debris collects. They gather in drains located in kitchens, basements, bathrooms, and sewer areas. The female flies lay their eggs in moist debris, and once the larvae hatch, they feed on that same debris. Drain flies can also become problematic behind wall spaces, inside of crawl spaces, or behind refrigerators where leaky pipes or other moisture issues are present.
