Seresto represents a major advance in the development of ectoparasiticides. The unique polymer matrix of Seresto provides dose adjusted release of two proven active ingredients: imidacloprid, a very potent insecticide, and flumethrin, a highly effective acaricide. Research into the efficacy of this combination has demonstrated that these two active ingredients work synergistically to significantly increase their efficacyagainst fleas. Laboratory trials confirm that the combination of imidacloprid and flumethrin is 100 times more effective against fleas than imidacloprid alone. Thanks to its innovative polymer matrix composition, the migration of active ingredients from the Seresto collar matrix to the surface adjusts depending on the concentrations of active ingredients within the lipid layer on the pet´s skin. This ensures a steady, low-dose release profile, providing optimal protection for up to eight months. In Europe and New Zealand Seresto is already available on the market since 2012.
