K9 Advantix II is a convenient monthly topical application that kills and repels fleas, ticks and mosquitoes, kills lice and repels biting flies. It’s specially formulated for dogs with imidacloprid, permethrin and pyriproxyfen for broad-spectrum protection against these ectoparasites that can transmit diseases to your patients. And because it kills through contact, there’s no biting required.

K9 Advantix II kills fleas on dogs within 12 hours of application. It kills re-infesting fleas from the surroundings within 2 hours and protects against further reinfestation for at least four weeks.
