What are IGrs and how do they work?
As an insect grows it molts, growing a new exoskeleton under its old one and then shedding the old one to allow the new one to swell to a new size and harden. IGRs prevent an insect from reaching maturity by interfering with the molting process. This in turn curbs infestations because immature insects cannot reproduce.

How do insect growth regulators work?
How Insect Growth Regulators Work 1 Chitin synthesis inhibitors: Chitin is a component of the exoskeleton. If chitin synthesis inhibitors are employed, when an insect molts it cannot form a new exoskeleton, causing the insect to die. It can also interfere with egg development. 2 Juvenile hormone analogs or mimics: During molting, the influx of the juvenile hormones will prevent the insect from forming into the next life cycle phase, keeping it at a larval stage and preventing the insect from maturing into an adult. 3 Anti-juvenile hormones: This will block juvenile hormone production, causing young larval stages to molt too soon into a non-functioning adult.

IGRs are especially useful during “clean-outs” or intensive service. Any missed cockroaches or other insects left after the treatment will be affected by the IGR and will not be able to reproduce.

What is the effect of IGRs on cockroaches?
Cockroaches exposed to IGRs (top row) exhibit twisted wings and molting inhibition. Other IGRs are chitin synthesis inhibitors.
