Activyl Spot-On for Dogs and Cats are spot-on 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.
