If bed bugs walk over dried Gentrol IGR, does it work? Or does it have to be sprayed on a live bedbug?
Does it work with all roaches? If yes, which ones?
Gentrol IGR does not have to be applied directly to bed bugs or roaches to work. It has a residual that can last up to 4 months, so it can be picked up by bed bugs, roaches, drain flies and pantry pests long after it dries. It will work on all species of roaches.
