K9 Advantix II combines imidacloprid and permethrin to repel and kill ticks, fleas, and mosquitoes that may cross your dog's path. Each ingredient begins to affect pests through contact, attacking parasite nerve cells at different sites. When combined, the two compounds overwhelm the parasite's nervous system.¹ This leads to rapid paralysis and death of the parasite.
