Review on American Bio Systems Drain Gel Flies by Angela Jones

Works exactly as advertised. Watch the video to learn how to apply. We had drain flies in the bathroom from a bathtub that wasn't being used. First, I tried salt, baking soda, and vinegar, which is a widely recommended trick. This was a temporary fix that only worked for a few days. The drainage gel got rid of all the flies on the third day of 5 days of use. A month with no problems. We will definitely use that in the future. I was worried the gel might smell but it is odorless. Huge plus!
