What is Activyl?

Activyl is indicated for the treatment of fleas (Ctenocephalides sp.) on cats.

What is the active ingredient in Activyl?

Activyl contains indoxacarb, a molecule with an innovative mode of action for flea control.

How does Activyl work?

Activl is the first flea control product that works through a process of bioactivation. When a flea is exposed to Activyl on the skin of a cat it ingests the active ingredient. Enzymes in the flea's gut bioactivate the Activyl into a highly potent chemical that blocks the flea's nerve impulse transmissions resulting in its paralysis, inability to feed and ultimately death. Because Activyl's active ingredient is metabolised differently in insects versus mammals your pet cat are not affected at all because it only becomes active once in the flea.Activyl bioactivation 

How often is Activyl applied?

To break the flea life cycle Activyl is applied directly to the skin every 4 weeks. By doing this Activyl ensures that fleas that jump onto your pet will stop feeding, become paralysed and die. In addition Activyl controls the immature stages of the flea's life cycle in the environment and so prevents reinfestation. Studies have shown that Activyl is still 100% effective at 30 days after application.

From what age can Activyl be used?

It can also be used on cats and kittens from 8 weeks of age.

Should Activyl be used differently on long and short-haired pets?

The simple answer is no! Activyl moves through the oily coating of the cat's skin in exactly the same way in long and short-haired breeds. To provide the best care for your pet the correct product for your cat based on its weight must be used though.

How quickly does Activyl work?

Activyl starts killing fleas within 8 hours and at 12 hours after application 90% of fleas are dead. Importantly this speed of kill is maintained for a full month. 

Is Activyl water fast?

Activyl has been tested in cats to make sure it is not easily rinsed or washed off. It is quick drying and it remains effective after shampooing and swimming. Bathing your pet is not required prior to applying Activyl however your pet should not be allowed to swim or be shampooed within 48 hours after treatment.

Activyl tile 1Can Activyl be used on pets with itchy skin?

Activyl can be used in the management of pets with very itchy and inflammed skin due to flea bites - also known as flea allergy dermatitis.

Can I use Activyl all year-round?

Fleas are often a year-round problem and so Activyl should be applied every 4 weeks throughout the year.  

Can I use Activyl in pregnant or lactating animals? 

No informationis available on the safety of Activyl in breeding cats of either sex, or pregnant and lactating queens.
