How Roach IGRs Work

Insect Growth Regulators (IGRs) prevent insects from completing their normal development to the adult stage. For insects with gradual metamorphosis, such as cockroaches and bed bugs, the impact is on the last nymphal instar, causing adults to have twisted wings (cockroaches), darkened cuticles, and non-functional reproductive organs. Gentrol® products contain the IGR (S)-hydroprene which is a synthetic copy of a naturally occurring insect biochemical. The Gentrol® product line works as an effective roach IGR by preventing the nymphs from developing into reproductively functioning adults.

Using IGR technology with the translocating active ingredient (S)-hydroprene, Gentrol® products are an insurance policy to prevent future reinfestations and callbacks for cockroaches with formulations designed to reach the variety of areas where roaches hide.
