Seresto is a unique new flea collar that lasts for 8 months. During this time, the collar continuously releases a low dose of the two active substances, Imidacloprid and Flumethrin, keeping your dog protected from fleas and ticks.
The two active substances are distributed via the collar over the skin and fur of your dog. The collar protects against, and kills, ticks. We recommend removing any existing ticks on your dog prior to putting the collar on. In addition, Seresto protects against the development of flea larvae, and can be used as a treatment for lice infestations (Trichodectes canis). In the following video, the function of Seresto is explained.
