Activyl Flea and Tick for Cats

Activyl is a monthly spot-on flea treatment for all breeds of cats. The fast acting, waterproof treatment kills adult fleas and destroys flea life cycle through the bio-activation process. Easy to administer, the fragrance free topical treatment starts killing parasites within 8 hours of application. It provides absolute protection against fleas and remains effective even when exposed to sun.  

How it works?

Manufactured by Merck, Activyl is a highly effective flea prevention and control treatment that contains indoxacarb as the active ingredient. It kills fleas and destroys the flea life cycle through a unique process called bio-activation. When applied, activyl remains stored in the lipid layer of the pet’s skin. When the flea bites the pet, it absorbs the active ingredient indoxacarb.

The unique property of indoxacarb is that it is fully activated by the enzymes present in the fleas. Once it is fully activated, it damages the central nervous system of the flea leaving her paralyzed and dead at the end. The fast acting, odor free treatment starts killing fleas within 8 hours of application and remains effective for an entire month.

Being waterproof, it stays on the pet’s body even after bathing, swimming or prolonged exposure to sun.
