Fleas are the most common external parasite found on pets, and can irritate your pet with constant itching and scratching, hair loss, or flea allergy dermatitis.
Activyl® Topical for Dogs and Cats stops fleas from biting to give your pet quick relief, and breaks the flea life cycle to prevent new fleas from developing. Activyl can be purchased at your veterinary clinic, online or at select retailers near you, to ensure your furry family member gets the best care.

Activyl Topical for Dogs and Cats are topical products that use indoxacarb and a mode of action that uses enzymes inside the flea to activate serious flea-killing power. They are applied to a small area of skin but soon spread on the skin and coat. Fleas don’t have to bite to take up Activyl, simply coming into contact with the skin is enough.
By stopping flea eggs and larvae, in addition to killing adult fleas, Activyl breaks the life cycle. This is effective at both killing and preventing infestations.3,4
