    • Kills adult fleas, ticks, flea eggs and larvae
    • Brings down ticks that may transmit diseases
    • Provides waterproof effectiveness
    • Offers a mighty killing force for a full 30 days
  • FRONTLINE TRITAK For Dogs has 2 ingredients, fipronil and cyphenothrin, that kill fleas fast.
  • But that's not all. It has a 3rd ingredient, (S)-methoprene, to bring down flea eggs and larvae, too. So you can be sure you're preventing and controlling an infestation.
  • Because adult fleas make up only 5% of a typical flea population,2 your dog also needs protection against eggs and larvae to break the flea life cycle.
  • Once fleas emerge, they waste no time looking for prey to feed on. Having landed on your pet, untreated fleas will attack, then reproduce.
  • That's why you need the triple-action formula of FRONTLINE TRITAK For Dogs. It kills fleas quickly1 so fleas have less time to bite your dog.
  • Fleas attack cats, too. That's why we also offer FRONTLINE TRITAK For Cats. It has 2 ingredients, fipronil and etofenprox, to kill fleas in as little as 1 hour3 so they have less time to bite. Plus, it includes a 3rd ingredient, (S)-methoprene, to kill flea eggs and larvae.
  • To see how to apply, read the instructions. And remember, always use FRONTLINE TRITAK For Cats on cats only. 
  • If you see flea dirt (tiny black specks of dirt) in your pet's coat, treat all your pets for fleas.
