How to end a Drain Fly Infestation and Take Further Steps to Keep it From Happening

end a drain fly infestation

Flies are common pests found in different households. There are actually distinct kinds of fly species. A prevalent fly specie that can be seen in drains and plumbing systems are drain flies. As its namesake, drain flies are found in drains and it just so happens that the drain linings are its favourite breeding spot.

While the drain flies themselves aren’t harmful; the sewage wastes they carry can harbour harmful pathogens (but this rarely happens). Drain flies can produce a lot of eggs (around 10-200), and if you’re unable to keep the flies from laying more eggs; you drains will be overrun by these annoying insects. End the drain fly swarm now by following these tips. In addition, we will also cover methods to keep your drains free from flies.  


You need to be familiar with the flies and know where to find them

It’s important to know that drain flies have a clear distinction between other fly species. While you can confuse drain flies with any small flying insect; you can actually see the main differences between other species. Most small flies look like the small versions of houseflies with odd colours, but a drain fly can be easily distinguished from other flies since it looks more of like a tiny moth with clunky flight patterns.  

You can know the definite spawn area of the drain flies if you noticed them flying or hanging on one specific drain. Other than that, larvae that are coming out of the drains are another indicator that particular drain is the breeding ground of the flies. However, some of you might face a situation in which there are many drains in the area.

There’s an easy way to pinpoint which drain the flies are occupying. But first, you need to get a tape that must be transparent. Once you acquired the tape, stick it onto the drains but you must not fully envelop the drain opening. Give a little bit of opening or else; the flies will find another way and you won’t have any proof of their breeding ground. After you’re done placing the tape, leave it for around five days. If there are flies caught on the tape then that particular drain is where you must focus your drain-cleaning efforts.  

Destroying the breeding grounds

Drain flies lay their eggs on obstructions in the drain lining like hair, gunk, and other residue. Removing a drain fly breeding ground is basically the same with cleaning and clearing drains. Pour boiling water into the drain to slacken the residues that are stuck. The next step is to first use a plunger to suction out the obstructions. To make sure there aren’t any grime and dirt that remain, get a drain snake to clear out the excess clogs. Pour a drain-cleaning solution to freshen the drain lining and remove the bacteria. Do the whole cleaning process if necessary. The best way to keep a drain fly infestation from occurring is to simply clean and maintain all the drains in your household.
