Drain Fly

Drain flies are a small moth-like insect that can be a real nuisance in large numbers. Drain flies are also known as “moth flies”, “sewage flies”, and “filter flies”. The most obvious sign of a drain fly infestation is usually a sighting of the adult flies, typically found on kitchen, bathroom, or basement walls. If left alone, an adult drain fly will live approximately two weeks.



Drain flies, also known as moth flies or sewer flies, are small, hairy, moth-like insects measuring 2 to 5 mm long depending on the species. They are weak fliers and are often seen walking near breeding sites.


Females lay 30 to 100 eggs in masses on the surface of breeding medium. 

​Drain flies are known for laying eggs in wet organic matter such as the build up that can be found in poorly maintained drains, wet manure, sewage, and compost piles. Depending on temperature, the eggs hatch in 30 to 48 hours. The larvae, also known as maggots, are legless, 3.5 to 10 mm long, pale in the middle and darker in color on the ends.


Surprisingly, drain flies are not known to transmit any diseases to humans. However, an untreated infestation will eventually lead to hundreds of flies that can make residents and visitors uncomfortable. Flies of any kind will leave a poor impression on the professionalism of businesses and their ability to maintain the establishment.
