Repels and Kills Fleas, Ticks, and Mosquitoes Before They Bite
K9 Advantix II is a trusted monthly topical treatment for dogs that not only kills but also repels fleas, ticks, and mosquitoes on contact — meaning they don’t have to bite to die.

How It Works
K9 Advantix II is a topical flea and tick preventative that combines imidacloprid, permethrin, and pyriproxyfen. It kills and repels fleas, ticks, and mosquitoes on contact—before they can bite. Pyriproxyfen also disrupts the flea life cycle by targeting eggs and larvae. The formula spreads through the skin’s natural oils and remains effective for 30 days.
Who It’s For
Best for dog owners seeking comprehensive, non-oral protection against multiple pests. Especially beneficial in tick-heavy regions or during high-risk seasons. Not for use in cats—permethrin is toxic to felines. Also not recommended for puppies under 7 weeks of age or dogs with known skin sensitivities without veterinary approval.
Real-World Use
Pet owners love K9 Advantix II for its ability to stop pests before they even bite, especially in regions with heavy mosquito or tick populations. It’s popular among hikers, outdoor adventurers, and suburban pet parents alike for keeping dogs protected with a single monthly dose.
K9 Advantix II delivers broad, dependable protection from pests that threaten your dog’s comfort and health — all in one easy monthly application.
