Insect Growth Regulators. Insect Growth Regulators or IGR inhibit the growth of immature insects. If an insect cannot mature into an adult, it cannot reproduce. Flea eggs and larva never reach adult stage; mosquito larvae die before reaching adult stage; roaches and other insects cannot molt properly, which inhibits their ability to reproduce.
