Killing with IGRs

Only about 5% of the flea population is comprised of adult fleas, while the remaining 95% are in the early development stages (flea eggs, flea larvae, and pupae).
Insect growth regulators (IGRs) prevent flea larvae eggs from maturing into adult fleas.
This process interrupts the flea life cycle from progressing since the fleas are no longer able to reproduce.

Killing flea eggs and flea larvae before they mature into adult fleas is the best way to eliminate a flea infestation.
