With its innovative delivery system, Seresto offers a breakthrough in flea and tick protection for dogs or cats for eight months.


  • Kills Fleas
  • Repels and kills ticks
  • Non-greasy, odorless, easy-to-use
  • Water resistant
  • 8 months of control!

How it Works

Inside the unique polymer matrix of Seresto are two active ingredients:

  • Imidacloprid has been used in products recommended by veterinarians for years to control flea infestations.
  • Flumethrin works to repel and kill ticks. Already used in Europe, this effective active ingredient now comes to the US.

Sustained release technology

Seresto works similarly to a monthly topical, but as the active ingredients wear off over time, a new supply is continuously replenished in low concentrations. The active ingredients spread from the site of direct contact over the skin surface.

NOT for use on dogs under 7 weeks old

Selection of the store only applies in the cart/checkout.

    Been using the Soresto collar for 9+ years. Have never found a flea or tick on my dog. My dog has never had a reaction to the collar. Excellent product! The only thing I see happening is with the clip-on reflectors, they sometimes break or fall off when my dog yanks on the tie out while in the yard.
