Overview
for Drain Fly
Drain flies are small, fuzzy, moth-like flies that breed in the gunk lining your drains — so if tiny "moths" keep loitering on the bathroom wall, your plumbing has roommates. They belong to the family Psychodidae, with *Clogmia albipunctata* the common drain-dwelling species; "moth fly," "filter fly," and "sewer fly" all name the same group. The good news: they don't bite, and the fix is usually a scrub brush, not a spray can.
