What Are Drain Flies?

2/27/2020 (Permalink)

You may have noticed small flies around your kitchen sink or shower, and wondered where they came from.  You may have a very clean home or business, so their presence is strange. These flies are known as sewer flies, sink flies, and most commonly, drain flies. They thrive on stagnant, shallow water, typical of drains attached to sinks and showers.  They are especially fond of sinks, as there can be organic matter for them to feed on.

How To Locate The Source

If you suspect that you have these pests present in your home, there are ways to find out where they are coming from. In the evening, place tape over the drains in your home or business.  If the flies are originating from any of your drains, they will stick to the tape. This will show you what areas need to be addressed, as well as the extent of the issue.  

How To Eliminate The Flies

With a deep clean, the issue may be resolved within a week.  Do a thorough cleaning of the problem area, whether it is yoru sink or shower.  You can also pour boiling water down the drain a couple times daily. This may work as well.  For a persisting issue, you can turn to drain cleaners such as Drano. This won't necessarily kill the flies, but will dissolve any organic matter that the flies may be feeding on.
