K9 Advantix® II for Dogs is a waterproof topical insecticide for use once monthly on dogs and puppies 7 weeks of age and older. This powerful spot-on flea control product contains 3 highly effective active ingredients: impidacloprid and permethrin, which kill adult fleas and ticks, and pyriproxyfen, an insect growth regulator that prevents flea eggs and flea larvae from developing. Together, these ingredients work to prevent ALL stages of fleas from developing and bothering your pets and your family.

In addition to breaking the flea life cycle, K9 Advantix® II for Dogs provides long-lasting tick protection by eliminating 4 main species of ticks: deer ticks (which may carry Lyme disease), brown dog ticks, American dog ticks and lone star ticks. It also kills mosquitoes and chewing lice, and repels biting flies.

Consult a veterinarian before using this product on breeding dogs, nursing puppies or pregnant dogs.
