Drain Fly


Drain flies are an absolute headache to anyone they come into contact with. These flies like to hover in and around your drainage areas, and create major frustrations for every home they invade. Drain flies are very small and, when under a magnifying glass, are known to be covered in furry hair. They are more of a nuisance pest than anything. If drain flies enter your home, they can increase in population, and if not treated soon enough, you will have a major problem that should be tended to immediately. Call the real Nashville Pest Control, and get rid of your drain fly problem today!

Appearance and Life-cycle:

As previously stated, drain flies are very tiny. And when under a magnifying glass, it will seem as if they have furry hair on their bodies. They are 1/5 to 1/8 of an inch in size, and they have large horizontal wings that cause them to be weak fliers. Whenever they rest, they fold their wings across the backs of their bodies like a roof. They are gray to black in color. Female drain flies can lay their eggs anywhere that there is decomposing food materials. Flies can undergo generations within one week, however 2-3 weeks is more typical to complete a generation. Usually, drain flies lay their eggs in the drains, and when the drain is pulled up, the larvae are found in the film.

Habitat and Behavior:

Drain flies are normally found wherever there is decomposing materials, like those in a kitchen sink drain. They can also be found in basement drains, crawlspaces, bathroom drains, etc. Anywhere that has decomposing material, drain flies are probably present. They usually are more active during the night hours. They also feed on organic materials and sewage.

Level of Danger:

Although these flies feed on decomposing matter, they are of no danger to humans. They do not bite, nor do they sting. They, surprisingly, do not transmit diseases either. If drain flies are not treated properly and promptly, they can become a bigger headache than seeing just one. The longer you let one go without treating, the more drain flies that will invade your home, and make it their own.

Signs of Infestation:

Of course, the most obvious sign of infestation would be seeing them around your draining areas, such as your kitchen, bathroom, and basement areas.


One way to get rid of drain flies is by reducing the amount of moisture and organic debris that could potentially attract drain flies. Like preventing most pests, you should seal all cracks and crevices to prevent them from getting into your home. Also, make sure your gutters are cleaned out and you remove any decomposing debris away from the house that could also attract drain flies. However, the best thing you can do to prevent them, is by calling the real Nashville Pest Control. They have experienced and professional exterminators that will help you rid of these annoyances.
