I have drain flies and want to get rid of them. Both products seem to do the same thing. Is one stronger than the other? Is the Biodrain more environmentally friendly?
DF 5000 Drain Fly Gel and Invade Bio Drain are pretty much the same and will do the same job for you. The main difference is that they are made by different manufacturers. Both products are very environmentally friendly.
