Activyl Flea Control for Cats

Activyl for Cats is an inventive product from Merck, a once-a-month spot-on topical solution for total flea control in cats. It kills adult fleas and stops flea larvae and eggs from developing, thereby breaking the flea’s lifecycle. Activyl spreads through your pet's skin and when a flea lands on your pet, it takes up the active ingredient and causes the enzymes in the flea to change. The flea becomes paralyzed and unable to feed and ultimately dies.

Product Specifications

Activyl for Cats is an OTC product available in two packs: for cats and kittens weighing 2-9 lbs in 0.51 ml (0.02 fl oz) applicators and for cats over 9 lbs in 1.03 ml (0.03 fl oz) applicators.


Activyl contains Indoxacarb, an active ingredient with an innovative mode of action for flea control called bioactivation by which the active ingredient is activated using enzymes inside the flea.
