Activyl Product Description

Activyl® is a new spot-on flea treatment that works through bioactivation. This means it only switches on inside the flea, to deliver full flea-killing power.

Activyl® breaks the flea life cycle and prevents reinfestation

Fleas can quickly become a significant problem for dogs and cats and the rest of the family. Since each female flea can produce 40 to 50 eggs or more a day, even just a few fleas can infest your entire home in a matter of days.


Apply Activyl® monthly to break the flea life cycle. This:

  • Ensures that the fleas that jump onto your pet will soon stop feeding, be paralysed and die

  • Kills eggs and larvae in the environment and prevents reinfestation.

  • Helps in the management of pets that develop itchy skin (flea allergy dermatitis or FAD) due to flea bites

  • Kills fleas fast

Activyl® starts to work quickly after it is applied. Studies show that Activyl® kills 90% of fleas within 12 hours of first application. Thereafter, Activyl® kills 99% of newly arriving fleas within 8-12 hours for a full month.

Activyl® is approved for use in:

  • Dogs and puppies over 4 lb from 8 weeks of age

  • Cats and kittens from 8 weeks of age

Directions of Use


  • DO NOT use on kittens under 8 weeks of age
