Activyl Flea Treatment For Cats

What is Activyl?

Activyl is a unique flea treatment for cats. The spot-on kills adult fleas and prevents flea allergy dermatitis. It is the first flea control product to use metabolic activation or bioactivation to kill fleas. The topical monthly treatment disrupts the flea life cycle by restricting the development of flea larvae. This assists in the environmental control of flea infestations and helps control flea re-infestation for up to four weeks.

It is safe to use in cats and kittens from eight weeks of age.

How does Activyl for Cats Works?

Activyl contains active ingredient indoxacarb. When applied, indoxacarb is taken up by fleas where it is converted into a highly active metabolite. This bioactivation process causes fleas to stop feeding and they die within hours. It kills adult fleas and destroys flea life cycle by inhibiting flea eggs and flea larvae. Activyl is quick drying and fragrance free.
