Why Are Drain Flies In My House
Drain flies are attracted to small amounts of stagnant water they find in plumbing pipes, sinks or other drainage areas. The flies feed on tiny amounts of bacteria, algae and sewage, so you can find them gathering around kitchen and outdoor sinks, shower and bathtub drains, basement sinks, sewers and septic tanks. Drain flies love sinks and drains that dont get used much, so if you have a guest bathroom or a shop sink in a garage, drain flies are more likely to find the pool of dirty water they need to feed and breed. They come into your house from the outdoors when they smell water and they set up shop in a drainpipe.
The presence of drain flies doesnt mean you have a dirty house or mucky pipes. Drain flies can pop into a clean kitchen while you are away on vacation. All they need is a little undisturbed water in the crook of a drainpipe and a few days with no human disturbance.

This is usually pretty easy. If you see one, theres a good chance that theyre coming from the nearest drain. To find out for sure, grab a piece of tape, lay it sticky side down covering about ¾ of the drain in question, and continue checking it for the next few days. If they are coming from that drain, there should be flies stuck to the tape.

If you suspect a pipe or drain is always a little wet, start there.
