Drain flies are these tiny, relatively slow moving flies that can become quite the nuisance. They are slow enough to be killed easily with a hand or a flyswatter. Killing them is not the problem. The problem is that they seem to regenerate like a bad guy in your favorite 80’s Nintendo game. They reproduce quickly and you can bet that wherever they are coming from there are dozens more hatching and ready to take over the job of annoying you.
So, what are theses pesky little flies? They are tiny insects that are covered in a plethora of tiny hairs. That’s why when you smash them they turn into a smudge. They are about 1/8 of an inch long. They are found in drains and open swage lines.
The fly may be an indicator that something more sinister is at play. If you have a pipe leak in the walls, you may start seeing these flies pop-up out of nowhere. If you are seeing these flies and are also noticing strange new smells in your house it may be a good idea to call a professional plumber.
The flies feed on organic waste that collect in drainage and sewer lines. Make sure you are not confusing these with fruit flies. People often mistake one for the other.
The best way to get rid of this fly is to eliminate the food source or patch the hole from which it is emanating. You can use over-the-counter products to clean drains. You can also use vinegar and baking soda. It is recommended that you clean up very meticulously around the drain and sink area. Any tiny patch of grease or organic material may be a food source for this annoying fly.
Because this fly hatches in sewage, it can spread germs throughout your home. So, other than this particular insect being an annoyance, it can actually be unsanitary for you and your family.
