Insect Growth Regulators. Insect growth regulators (IGRs) are insecticides that mimic hormones in young insects. They disrupt how insects grow and reproduce. IGRs can control many types of insects including fleas, cockroaches, and mosquitos. Although they are rarely fatal for adult insects, they can prevent reproduction, egg-hatch, and molting from one stage to the next.
