How Can Flies Live in Drains?
WouterFlies living in drains can be difficult to spot, due to their small size. Their body is covered in long hairs. Despite this, they can be easily trapped using a simple trap. Place a clear plastic cup with a light coating of petroleum jelly or oil over the drain for several days. This will help you identify the breeding area. Alternatively, you can use clear tape to cover the drain.
Drain flies are attracted to standing water and bacteria build-up. They breed in any drain, and you might notice them after a couple of days or when you leave the house for an extended period. You may also find them in bathrooms or guest rooms. It is important to find out what is causing the flies to reproduce in your drain so that you can prevent them from infesting your home.
Drain flies live in a sewer or drain for at least one week. Their life cycle is typically eight to 24 days long, depending on the climate and temperature in your area. Adult drain flies can remain active for up to two weeks when nectar is available. If you notice a large number of adult drain flies in your home, this is a sign that your sewage drainage system is inefficient. Overflows in drains can create a breeding ground for the flies and can lead to a major infestation.
While drain flies are not harmful to humans, they can be a nuisance in your home. They breed fast and can cause damage to your pipes. You can kill the flies by cleaning your drains with dish soap and water.
