What causes drain flies?

Nuisance drain flies, sink flies, filter flies, sewer flies, or sewer gnats, is a family of true flies. They appear in large numbers and clusters, drain flies have hairy bodies and large wings may appear to look like moths in appearance

Drains flies are attracted to stagnant water in drain pipes and other drainage areas inside the home like floor waste, bathrooms that are not used often. They are small, gnat-like insects feed and breed in sewage or organic waste material they often build up along the side of tiles and drains especially in commercial kitchens where the food waste is not clean out daily.  They quickly reproduce.

The drain flies are a real nuisance because they infest in large numbers. Once inside, drain flies can spread bacteria from the unhygienic environment they live in, if not controlled they can contaminate food and are not known to spread disease to humans.

Drain flies can be controlled in your home by cleaning the drains in your home or business regularly.  A simple solution is to pour 2 kettles of hot boiling water into the drain every 2 days and then weekly.  You can also use a mixture of Baking Soda, vinegar, and salt followed by boiling water. Wipe down doors and windows, keep doors and windows closed as much as possible to prevent them from finding a way to drains and their breeding ground.
