How It Works Gentrol® IGR Concentrate travels deep into wall cavities, cracks and crevices, reaching the pests that other treatments miss. (S)-Hydroprene, the active ingredient, prevents pest larvae from progressing to the adult stage either causing sterility of adults or preventing the emergence of insects from the pupal stage — preventing future infestations. Stored product pests encounter (S)-Hydroprene the same way they encounter insecticides — contacting a treated surface. 16 oz. makes 16 gallons of solution. For roaches treat every 4 months. For Bed bugs treat every 2 weeks. For fruit and drain flies treat every 2-4 weeks.
