Product Detail: Activyl

Activyl for Dogs and Cats

Activyl for Dogs and Activyl for Cats are spot-on products that contain indoxacarb and a mode of action called bioactivation-it uses enzymes inside the flea to activate serious flea-killing power. They are applied to a small area of skin but soon spread. Fleas don't have to bite for Activyl to work; simply coming into contact with the skin is enough.

  1. 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 at home.
  2. How to use the product

    Activyl for Cats- Place the product at the base of the skull to help prevent your cat from licking it. Squeeze the applicator firmly, applying the entire contents directly onto the skin.

    Activyl for Small Dogs- Place the applicator tip against the skin between the shoulder blades. Squeeze the applicator firmly, applying the entire contents directly onto the skin .

    Activyl for Medium to Large Dogs- Apply entire contents of the applicator evenly to two, three or four spots on the back- from between the shoulder blades to the base of the tail. At each spot, part the hair and apply directly to the skin. Do not apply an excessive amount of solution at any one spot.

    This product appeared to be one of the best among all spot-on products that I've used in the past. I recommend this to everyone who wants to get rid of all those stubborn fleas.

    Great Product indeed

    It works, no flea issues since we started (6+ months now) Used to use Frontline, but my dog would have flea issues every month, and the cycle went on for the past 4 years. Frontline and all of the other top brands have chemicals that are known as carcinogenic to humans, and are used on our fields of produce as insecticide. I wanted something that wasn't part of the mass production of insecticides, and wanted to offer my dog something that I didn't feel bad about. No ticks found on my dog since using this, either.
