This powerful multi-parasitic repellent and killer offers broad-spectrum protection against fleas, ticks, mosquitoes, biting flies, and lice—without requiring a bite to take action.

Formulated with Imidacloprid, Permethrin, and Pyriproxyfen, K9 Advantix II provides dual-action protection by both repelling and killing pests on contact. This monthly, waterproof application is ideal for dogs living in high-risk outdoor environments, offering consistent protection across varying climates and parasite populations.
