Tips and products for your pest problem

No one likes dealing with flies of any kind, but drain flies can be particularly bothersome because of how quickly they reproduce in large quantities. Also called sink flies or moth flies, drain flies pose no health threat to human beings, but since just one fly can lay 300 eggs in less than two days, a drain fly infestation comes with a sense of urgency.

Fortunately, the remedies for ridding your sink of drain flies are easy and effective. And after the flies are gone, preventing their return takes just a few simple steps. In this article, we’ll discuss how to get rid of drain flies and the products you need to get the job done. Some of the featured products have multiple functions, including drain cleaners and fruit fly killers.

Finding the sources

Drain flies are drawn to stagnant water. While sinks and septic tanks are common gathering spots, they also can be found in compost piles, wet mops and buckets, storm drains or just about anywhere with standing water. If you can stop the water from pooling, you may be able to keep the flies from reproducing. Otherwise, you need to treat the site with natural or chemical solutions.

Preventing drain flies in the future

Cap off drains that are not used often to prevent flies from flying down them. Run boiling water or a cleaning solution down drains on a weekly basis where flies have been known to congregate. And keep mops and buckets dry and stored in areas that won’t trap moisture.
