Product Description

Activyl for Dogs is a once-a-month topical treatment for fleas. Unlike some flea treatments, Activyl doesn’t just kill adult fleas, it also stops flea eggs and larvae from developing. Breaking the flea life cycle is important, so your pet is not reinfested by new fleas developing from flea eggs and larvae in your home environment.
