We had a leak under our raised foundation which was fixed 3/1/17. The water had seeped quite far. We still have drain flies even though the rain has stopped and it has warmed up. They are even in our bathroom. I am killing 5-6 nightly. Will they ever go away?
Gentrol IGR Concentrate is an insect growth regulator not an insecticide. This product is used to stop the reproduction cycle of insects. It will not kill the insects. Gentrol can be used in conjunction with an insecticide to treat an infestation. If treating for drain flies we would suggest you use our Drain Fly Kit to get the best results.
