29 November

When it comes to household pests, you’re always on the alert for rats, termites, and cockroaches. But here’s something that might not be on your radar: drain flies and drain fly larvae. Have you ever been around septic tanks, a sink, a shower or bath, or a kitchen and noticed a tiny little moth-like fly (or 50) buzzing around?

These annoying moth-like drain flies typically shop in your bathroom drains, kitchen pipes, and garbage disposals—mainly if there’s much organic matter to feast upon. Are moth flies or drain flies harmful? No. But the real question is simple: How can you get rid of drain flies quickly and effectively? Is using a wire brush and pouring hot water into your drains enough for pest control? Or should you lure and trap them using plastic wrap?

How to Get Rid of Drain Flies For Good

First things first: don’t panic. As mentioned, you’re not the only one with sewer flies or a drain fly problem. And although they munch on the gross organic material that lurks in your drains and drain pipes, these little critters aren’t going to kill you.

Moth flies are not as alarming as mosquitos and standing water. And they aren’t going to endanger the structure of your home either, so drain fly issues are not to be a cause for panic. They have been known to trigger asthma symptoms in sufferers if inhaled at the very worst. So, they’re not that much of an emergency plumbing situation. There are far worse plumbing problems out there.

If you’ve discovered small flies or fly larvae in a shower or bathroom drain, it is most likely where they will lay eggs. Once the eggs hatch into tiny white larvae, it takes about 8-24 days to mature fully. Adult flies only span two weeks, unlike houseflies that live up to a month.

Even if your unused bathroom appears clean, without using or thoroughly cleaning it regularly, you’re laying the groundwork for a stagnant accumulation of the slimy stuff and stagnant water that the drain flies find so tasty. And if you can visibly see mould in your bathroom, it’s time to remove the rubber gloves.

Drain Fly Remedy #1: Trapping Drain Flies

Regularly cleaning and flushing your drains is a great way to prevent drain flies. But that solution will not help eliminate drain flies already entering your house.

For that, try this easy DIY recipe. In a bowl, add equal parts of water, sugar, and vinegar, and the secret ingredient: drops of dish soap. The drain flies won’t be able to resist it—and their consequences will be dire.

Drain Fly Remedy #2: Boiling water.

But wait! Shouldn’t we be trying to stop the drain flies at the same source? It’s all good and well to know how to kill drain flies once they’ve crawled out of the drain, but what about the ones still down there?

Boiling Water

For that, the solution really couldn’t be more straightforward. Hot water is your answer! The main problem is usually stagnant drains and pipes that are not often used, and the best way is to pour boiling hot water down the kitchen sink or drain. Not only is this a great way to kill the drain flies, but it will also help to clear your drains of the gunk drain flies love to eat. Add baking soda and vinegar (apple cider vinegar or white vinegar) to the clear-the-drain ingredients! Let this mixture sit in your drain overnight. The baking soda with white vinegar will surely do an excellent job and clear and clean pipes.

Drain Fly Remedy #3: Go The Extra Mile.
