I was told to spray one in the drains and the other in cracks on counters. Which one do I use for what?
You definitely want to spray the Gentrol Aerosol down the drains. This product will control the growth and reproduction of the flies - keeping them from multiplying. The Phantom Aerosol is a crack and crevice treatment. This product will kill the flies that are flying out and about that land on a treated area. You may also want to consider DF 5000. This product is a gel designed specifically for drain flies. Pour 4 oz of the product down each infested drain each night for 7-14 days.
