Onguard Plus is a topical treatment containing two active ingredients Fipronil and (S)-Methoprene. When fleas and ticks come in contact with Fipronil it binds to the insect leading to its death. (S)-Methoprene acts like an insect hormone and disrupts egg-laying, egg-hatching, and development into an adult.

When applied once every 4 weeks, these active ingredients spread from the application site onto hair and skin where it enters the glands near the hair follicles and is then slowly released for 4 weeks. This dual action provides your pet one month of protection from incidental encounters with fleas and ticks.
