Drain flies, also known as moth drain flies or sewer drain flies, are moth-like insects covered with small hairs. Typically, 1.5 to 5 mm in size, they can be brown, grey or black. The drain fly is not a strong flyer and will generally jump or only fly short distances.
Drain flies live and feed on decomposing organic matter and sewage. Preferred habitats include clogged pipes in kitchens and bathrooms, septic tanks, sewers and compost.
A large amount of flies in the home typically indicates a problem with poor sewage drainage or overflows, which can become a continuous breeding ground. An untreated infestation will eventually lead to hundreds of flies.
Female drain flies lay anywhere from 30 to 100 eggs, which hatch into drain fly larvae. Drain fly larvae can mature to adulthood within one to four weeks.
For prevention and control of drain flies, stop breeding sites from even starting. Ensure all sinks and drains in the house drain properly. If sinks and drains do become clogged, treat immediately. Re-gout bathroom tiles to prevent water seepages into the wall. Clean dirty garbage bins.
If you already have a drain fly infestation, contact the experts at Environmental Pest Control who know how to get rid of drain flies. A licensed technician will find the breeding site and apply the appropriate drain fly killer treatment.
