Seresto™ flea and tick collar

Active ingredients are stored in the collar's unique polymer matrix and released in low controlled doses, as needed, to maintain effective concentrations on your pet. Easy to fit, and can be loosened as required in growing puppies and kittens.

At Elanco, we've developed Seresto™ with your pet’s health and well-being front and centre. Over 25 million Seresto™ collars have protected pets around the world from pesky fleas and deadly ticks and the diseases they spread.

With many flea & tick treatments, the active ingredients get absorbed into your pet's bloodstream. This means fleas & ticks need to bite your pet to get a deadly dose. Seresto™ is different! The active ingredients work on the outside of your pet, so fleas and ticks don’t have to bite your pet to die.
