K9 Advantix Flea Treatment for Dogs

K9 Advantix is a monthly spot-on treatment for fleas, ticks, lice, mosquitoes, sand flies, stable flies and insects. Its effective action destroys existing fleas within 24 hours and 98.5% ticks within 48 hours of application. Suitable for all breeds of dogs, this waterproof treatment repels ticks from sticking on the treated dog’s body.

How it works?

A Bayer product, K9 Advantix is a highly powerful monthly spot-on treatment for 7 weeks and older puppies and dogs. It kills and controls broad spectrum of external parasites including fleas, American dog ticks, brown dog ticks, lone star ticks, deer ticks, mosquitoes, biting lice, flies and insects. It uses ‘hot foot’ mechanism to prevent ticks from being attached to the treated dog’s body.

The joint action of active ingredients Imidacloprid and Permethrin kills fleas within 24 hours and ticks within 48 hours. The newly formed fleas and tick life stages are destroyed within 2 hours. The ingredients obstruct the sodium channels of the parasites leaving them paralyzed and dead.
