Drain flies (AKA. Moth flies) are small (avg. size about 2mm) flies generally gray in color and easily recognized by their thick coat of hairs, which cover both the body and wings. Another key trait is their habit of holding their wings pitched over themselves at rest. Adults are weak fliers usually found on walls near kitchen and bath fixtures and basement sumps. Moth fly larvae breed in the gelatinous film that lines drainpipes, water traps or in any moist (not flooded) situations where decaying organic material is present.
