Drain flies are categorized as small to medium-size flies, and are approximately 1/8”-1/4” in length. They are usually black in color, but may also be a dark brown, and they have numerous hairs on their bodies and on their wings, which makes them resemble a moth. Hence, they are also referred to as “moth” flies.
Drain flies are usually located around dark, moist areas where they have a source of food, which is often decaying matter, such as feces. They are very common around sewage treatment facilities, or in restrooms, under wet kitchen cabinets, mop closets, or other similar places where moisture and decaying matter is present. The drain fly is not a strong flier; therefore, it will often remain around the area where breeding occurs.
Drain flies do not bite, but they can be a nuisance because of the sheer number of them that are located in a breeding environment.
Since Drain flies are often located in hard-to-reach plumbing pipes, or in drainage systems, the assistance from a professional is often recommended. Persistence is a key ingredient to eradicating a Drain fly infestation, along with the appropriate type of cleaners or pesticides.
