In this article, you’re going to find out what’s causing drain flies, what they’re attracted to, and the most common areas they tend to inhabit! So keep reading to find out everything you want to know!
What Causes Drain Flies?
There are 4 main causes of drain flies. And knowing all the reasons can help you identify and look for other areas in your home where drain flies may be inhabiting. With that being said, here are the 4 main causes of drain flies in your home.
First of all, drain flies are going to be attracted to any areas that are damp or have standing water. Shallow dirty water is normally their go-to, and this can be found all around your home, both inside and out.
Standing water and stagnant water often house decaying organic material, which drain flies love to eat.
A Food Source
And of course, on the subject of eating, drain flies are going to thrive anywhere there’s a food source as well. One of the reasons they love drain pipes is because they’re often full of organic material they can eat, such as old food, soaps, and even hair.
Drain flies also love humidity. You should now be beginning to see why drain flies love the drains and pipes in your home so much. They provide everything they’ll need to thrive. Not only are they damp and full of food.
But any standing water in the pipes is going to create an incredibly humid environment where drain flies are going to thrive.
However, when you begin to think on a larger scale, you can understand how drain flies end up inhabiting entire rooms (such as your bathroom) when they aren’t aerated properly.
Although they’re more active at night, drain flies love light as well. Any light source is going to help them navigate, and just like moths, if they notice a light source, they’ll often fly directly towards it!
Why Are Drain Flies Attracted To This?
Drain flies are primarily interested in eating and breeding. So any area that is humid enough with plenty of standing water and build-up of organic matter is going to be the perfect place for both of these things to happen.
And the rate at which they’ll be able to lay eggs is astounding. Each drain fly can lay between 10-200 eggs which hatch in about two days, and then after another couple of weeks, they reach adulthood, where each adult can then produce another 10-200 eggs.
So as you can see, if you don’t deal with drain flies fast, they can get out of hand incredibly quickly.

Another common place to find drain flies is in moist compost. Once again, this is an area where drain flies find everything they need to breed. So if you have a compost bin, make sure you’re covering it completely to stop drain flies from being attracted to it.
If there’s a crack in your septic tank or the seals have broken, then your septic tank could be the reason that drain flies have started flocking to your home.
As you can imagine, garbage is going to be a massive attraction to drain flies, so if possible, keep garbage away from your home or completely contained in your home.
Mops And Buckets
If you have left mops and buckets out, then this could be another area of standing water that is attracting drain flies.
