Answer:

InVade Bio Drain works very well when there's a drain fly infestation but it does not include a pesticide to kill drain flies. InVade Bio Drain eats away naturally at the organic scum buildup in drains. Results can vary depending on the level of infestation. For best results, we recommend reading the Drain Fly Control Guide for further tips and information.
