Drain flies are brown or black in color. Their body and wings are densely covered with hairs, which gives them a fuzzy appearance. They are frequently mistaken for small moths since the wings are held roof-like over the body when at rest (hence the common name “moth fly”).
Range from 1/6 to 1/4-inch in length.
Drain flies are often associated with drains and are common at sewage treatment facilities. They are weak fliers and often appear to be jumping or hopping. Flight and mating activities normally occur in the evening hours when they are attracted to lights. Each female can produce around 100 eggs, and under optimum conditions development can be completed in about 2 weeks.
Drain flies may be found around bathrooms or kitchen sinks. They are common around wet areas and can even breed in sink and bathroom drain traps, in spite of the hot water, soap, and other debris that flow through them.
Bronchial asthma can be caused by inhaling fragments of dust from dead flies. Since Drain flies originate in filthy conditions, there is the possibility of disease transmission.
