Activyl for Dogs

What our customers say

"Great treatment for fleas"

"Activyl for dogs is the best flea treatment I have ever used. We have two dogs and Activyl keeps them flea free. It is a wonderful product. It is the most effective product on the market I have ever bought."

                 Linda B.

Activyl is a highly effective spot-on flea control treatment featuring indoxacarb and a mode of action that uses enzymes inside the flea to activate the serious flea-killing power.

Activyl really gets rid of fleas!

Both pets and people want a flea treatment that's really effective at killing fleas and preventing infestation, but how it works matters, especially regarding the impact on your pet and home. Ensure that your furry family member gets the best care possible. It's also quick-drying, fragrance-free, waterproof, and remains effective even after bathing.

Activyl breaks the flea life cycle

Unlike some flea treatments,  Breaking the flea life cycle is important, so your pet is not re-infested by new fleas developing from flea eggs and larvae in your own home environment.

Activyl for Dogs is the flea treatment just for dogs and Activyl for Cats is the flea treatment just for cats.
Both products kill adult fleas and also break the flea life cycle, so you're much more likely to solve your pet's problem for good.

Step 1: Application

Activyl spreads through your pet's skin and coat.

Step 2: Contact and Ingestion

When a flea lands, it takes up Activyl (no bite required).

Step 3: Activation

Enzymes inside the flea change Activyl into its fully active form.

Step 4: Flea-Free

The flea is soon unable to feed, becomes paralyzed and dies.

NOTE: At the beginning of Phase 4, fleas become disoriented and move in the coat of your pet, which makes them more visible to you. These fleas stop feeding, followed closely by paralysis and death.
