What Are Drain Flies?

Drain flies, also known as sink flies or moth flies, are tiny little pests no bigger than 5 mm. They have moth-like wings and round fuzzy bodies. Drain flies come in a variety of colors but usually range from pale gray to black. While their name may suggest they can fly, these little creatures actually can’t. Rather they take large hops to get around your home. They have a short lifespan but reproduce quick, so it’s best to deal with them as fast as possible. These pests like to hang around water sources, so you will find them congregating around your sinks, shower or bathtub drains, storm drains, wet mops, compost pile, sewer, and so on. They survive on the organic material found that builds up in standing water, which includes sewage and other contaminated waters. That’s why your drains are the perfect place for them to thrive and reproduce.

Mix everything and pour it down the drain. Leave the mixture to work it’s magic overnight. Then the next day, pour boiling water down the drain to clear out the mixture.

#DIY trap

Much like fruit flies, these pests are also a sucker for a good sugary temptation. But in reality, who isn’t? Take out a bowl and fill it with some water, sugar, apple cider vinegar, and a few drops of dish soaps. A weird combination, but trust us, the flies will love it. Place the bowl near the drain and wait. The sweetness of this mix will attract the flies and they will jump straight into the trap. Thanks to the thickness of the dish soap, once the flies are in the bowl, they won’t be able to get out. This method is great if you have a smaller infestation, but it may not be as effective if you are dealing with a lot of flies. For best results, use it in combination with some of the other methods.
