How does K9 Advantix II work?

K9 Advantix II combines imidacloprid and permethrin to repel and kill fleas, ticks, and mosquitoes. Both ingredients work on contact, attacking parasite nerve cells at different sites. Together these ingredients overwhelm the nervous system killing the parasite. Pyriproxyfen is an insect growth regulator. K9 Advantix II topical solution also repels biting flies and kills lice.
