What Are Insect Growth Regulators

Insect growth regulators (IGRs) are a class of specific insecticides, which do not directly kill insects when used, but hinder or interfere with the normal development of insects during the individual development period of insects, reducing the individual living ability and death of insects, and then causing the extinction of the population.

They are hormone-mimicking pesticides that target developing insects. They interfere with insect reproduction and growth. Fleas, cockroaches, mosquitos, and other insects can all be controlled with IGRs. Even though they rarely cause adult insect deaths, they can halt molting, reproduction, and egg hatching. Many IGR products contain additional insecticides that kill adult insects in addition to the IGR. IGRs typically pose little hazard to people.

Remember to read, comprehend, and adhere to all label instructions before applying any pesticides, including IGRs.

Start by identifying your insect. For some insects, some IGRs may work better than others.

IGRs do not kill mature insects, and increasing a product's dosage will not increase its effectiveness. Always adhere to the label's mixing directions.

Combine different control techniques. Insect problems are lessened through prevention, sanitation, and exclusion in integrated pest management.

IGRs can affect beneficial insects like bees as well. To lessen the risk to other insects, concentrate on specific problem areas.
