Sewer flies are small in size and have their wings pointing upwards. They multiply in a moist area and usually grow quickly in an area backed up with sewer water. Sewer flies do not transfer diseases as they do not bite, but they may transfer bacteria that is on their bodies. It is a good idea to wear a mask when walking in an area with sewer flies. It may sound funny but the sewer flies try to go into your mouth, this may not be written in text books but it is a first hand experience that is talking 
.
It is very important to get rid of a sewer back up as along with dealing with the sewer water smell, you will also have to deal with possible breeding of sewer flies. Many people might see sewer flies even though they do not have a sewer back up. This is possibly due to loose sewer caps. The sewer flies might be breeding in your main trap, if your sewer caps are not tightly placed onto your main trap, the flies can fly out of the loose area of the caps.
We have seen the sewer flies in kitchen sink drains as-well, so it is not a certain thing that sewer flies will only breed in sewer water. The sewer flies breed when the water is backed for a few days and the backed up water starts to turn “murky“. You can try to use any regular insect killing spray to get rid of the sewer flies but if the spraying does not work, you will have to locate the source of the flies. The source will more than likely be a sewer or drain trap. If you need help locating your sewer trap, we are here to help.
