Seresto® is different from conventional flea and tick collars. It employs a novel blend of materials, enabling a safe, controlled, low dose release of active ingredients over 8 months. This provides excellent protection for your dog, not only killing fleas and ticks but also repelling ticks before they bite – which helps to protect your pet from the diseases these parasites can spread.
Seresto® is a unique polymer matrix collar that offers a continuous supply of two active ingredients: imidacloprid and flumethrin for effective 8-month protection against fleas and ticks. That's one convenient, non-greasy, odorless flea and tick collar instead of 8 monthly treatments.
The active ingredients are stored within the collar. They are released in low concentrations and are distributed over your dog's hair and skin surface for 8 months. As active ingredients wear off over time, Seresto® for dogs continuously replenishes the skin and coat with a new supply of active ingredients. Fleas and ticks are killed through contact with the active ingredients — no biting required.
