How It Works
FRONTLINE Plus combines fipronil and (S)-methoprene — a powerful duo that:
- Kills existing adult fleas and ticks upon contact.
- Stops flea eggs and larvae from maturing.
- Prevents new infestations with monthly application.
Easy once-a-month application goes on the skin at a single spot, and the active ingredients disperse naturally over your pet’s coat.
