What causes drain flies?

The black or brown insects you see in your drain are most likely “drain flies”. Drain flies, also called phorid flies or sciaridae, typically lay eggs near sources of standing water such as sump pump pits. The larvae then develop underground for two to three weeks before they emerge and fly around looking for food–usually plants or other organic matter near water sources like sinks or showers.

Drain flies get their name from drains, and in particular the small openings that exist near the drain opening. They love dirty water and sump pumps can be a great place for them to breed. If you have a sump pump, then there’s a good chance that you might also have an infestation of drain flies.

What Do you Need to Get Rid of Drain Flies?

STEP FIRST

Clean the potential breeding sites

To get rid of an infestation of drain flies you need to clean the potential breeding sites. Eggs and larvae are not easy to drown. They’re highly resistant to heat and most water-borne chemicals, including bleach. The best way to get rid of this problem is by doing preventative maintenance on your sump pump system and cleaning it out regularly. The most reliable method to eliminate them is to clean the potential breeding sites from all the organic debris and slime that may have accumulated there.

If the problem persists, it’s probably because your sump pump pit is not clean and some eggs still remain in hidden areas that can’t be reached by regular maintenance. Check for leaks inside and under your home (the source of any leak must be eliminated); caulk holes through which flies could get into crawl spaces below decks, patios, etc. You can also repaire damaged screens; seal all cracks over air vents on exterior walls near ground level.

 

This will get rid of drain flies in most cases but if not then use one more items below:

  •  Insecticide. This can be a powder, aerosol or granules. You will want to get something that specifically says “drain fly” on the label and follow the instructions carefully.
  • Pit Cover. If you have a cover for your pit then this is a good idea to keep in place when not in use. This will help stop any new flies from coming in and breeding.
