Product Review

Gentrol IGR Concentrate travels deep into wall cavities, cracks and crevices, reaching the stored product pests that other treatments miss. Hydroprene, the active ingredient, prevents stored product pest larvae from progressing to the pupal stage of development, so the larvae die before they become breeding adults and future infestations. 1oz. bottle. Gentrol Concentrate should never be used to eliminate a roach population by itself. Gentrol will not kill roaches...it only prevents them from reproducing. You should use roach baits and roach sprays in conjunction with the Gentrol Concentrate.
