Drain flies are very frustrating. They come through the sewer when they smell food and can be a serious frustration to everyone in the house. The good news is they cannot harm you, they do not bite humans and they do not carry any kind of human transferable disease. However, they are not clean and if they land on your food they will dirty it and if eaten could cause food poisoning. This is about the worst thing that can happen with drain flies. Now the way to deal with them is giving your whole kitchen a very thorough deep cleaning. If that doesn’t work then you may need to call the city about the sewer near your home.
A great test a lot of people can try is taking a piece of tape and putting it over the sink drain. Make sure it covers it fully, use two pieces if needed. Then go to sleep. When you wake up take the tape off and see how many you caught. This will help you understand how many of them are entering your home a day and how serious you have to be about getting rid of them. It may seem intimidating but there are ways of getting rid of them for good.

If you need to use a chemical drain cleaner try getting something natural like Bio-clean which comes in a bulk container of powder you can mix with water. It is efficient and safe for the environment. XIONLAB also sells a very safe drain cleaner that will not raise the pH of the sewer and our freshwater supply.
