Drain flies breed and lay eggs in areas where there is decaying organic matter such as bathroom drains. To start the process of getting rid of this pest, you must thoroughly clean the drain where the worms have been spotted. Next, you should apply a product called Invade Bio Drain. The Invade Bio Drain gel will coat the inside of the pipe and will help breakdown built up organic matter. This process must be repeated every night for 5-7 days. In pipes where there is a lot of built up organic matter, a second week long treatment may be needed. If you have spotted adult drain flies in your home, you can spray a product called On-Time Metered Aerosol to help eliminate these breeding adults. You should place glue boards over each drain in the bathroom to capture any flying adults entering or leaving the drains. Using glue boards also helps monitor the level of infestation. We have all of these products combined into a Drain Fly Kit for your convenience.
