FRONTLINE TRI-ACT® is a spot-on treatment licensed only for dogs that contains fipronil and permethrin. It kills fleas and ticks faster than other non-prescription flea and tick treatments for dogs in the UK retail market.* It also provides long-lasting protection against flying insects (mosquitoes, biting flies and sandflies) as well as fleas and ticks, while also preventing home flea infestations.

FRONTLINE TRI-ACT® contains two active ingredients:

  • Fipronil, which kills fleas and ticks
