Have you noticed tiny, moth-like flies hanging around your sinks, showers, or bathtub? As it turns out, these bugs aren’t regular moths, nor are they your typical fruit flies. They’re drain flies — insects that can live up to three weeks and reproduce every 48 hours.
“Drain flies,” which are also known as moth flies, sink flies, sewer flies, or filter flies, tend to gather around standing water. So, what causes drain flies? We’ll answer this question below, along with how to get rid of drain flies for good.
These bugs, gray, black, or taupe in color, only measure up to one-eighth of an inch in size. They have moth-like wings and round, fuzzy bodies. Other features include tufts of fur and feather-like antennae on their heads.

Now you know what causes drain flies, but how do you know if you’re dealing with a drain fly infestation? You can check for larvae and use the duct tape test.
Your drain is likely a breeding ground for drain flies. You can check for larvae by removing the drain cover and cleaning off some of the grime. If this is where the drain flies are breeding, you’ll be able to find tube-like larvae on the drain cover.
To use the duct tape test, seal off the top of your drain with a piece of duct tape and leave it there overnight. The flies will get stuck on the tape as they try to fly to the surface. You should repeat this test a few nights in a row to understand the scope of the infestation.
