For outdoor use?
Gentrol IGR is not labeled for fleas and is not recommend for use outside. For outdoor flea control you should use our outdoor flea kit, which comes with an IGR that is labeled for fleas. IGR's do not kill adult fleas though, they only prevent immature fleas from maturing. The outdoor kit also comes with a product to mix with the IGR that actually does the killing of adult fleas.
