Seresto Flea & Tick Dog Collar

Seresto Flea & Tick Collar for Dogs

The Seresto collar for dogs repels and kills ticks and kills fleas through simple contact, which means they don't have to bite your dog before they fall off and die. Because ticks and fleas don’t need to bite and suck blood to be killed, there is a reduced risk of blood loss, pain, irritation, tick paralysis and transmission of infections.

Seresto contains two active ingredients: imidacloprid, which kills adult fleas, and flea larvae; and flumethrin, which repels and kills ticks. No other product has this combination of ingredients.

Seresto kills existing fleas on dogs within 24 hours after application. Once Seresto has been on your dog for 24 hours, reinfesting fleas are killed within 2 hours. Infestation prevention from new ticks starts within 48 hours after Seresto collar application. Reinfesting ticks are repelled and/or killed in as quickly as six hours (data on file).

It’s safe for use on puppies from seven weeks of age.
