4 x Bayer Seresto Kills and Repels Ticks Fleas Lice Collar Large Dog over 8 kg

To use Seresto® helps protect kittens, puppies, cats, or dogs how Seresto® works An effective combination Inside the unique polymer matrix of Seresto® are two active ingredients: Imidacloprid has been used in products recommended by veterinarians for years to control flea infestations. Flumethrin effectively repels and kills ticks, and kills larvae and nymphs. Flumethrin works together with imidacloprid to provide dual action against fleas and ticks. No other treatment has this combination of ingredients. Sustained release technology Seresto® works similarly to a monthly topical, but as the active ingredients wear off over time, a new supply is continuously replenished in low concentrations. The active ingredients spread from the site of direct contact over the skin surface. Bayer's polymer matrix technology is designed to slowly and continuously release the active ingredients over eight months. Seresto® is water resistant The active ingredients of Seresto® are contained within the Bayer Polymer Matrix, making it water-resistant. Seresto® remains effective following a shampoo treatment, swimming, or after exposure to rain or sunlight. Under normal conditions, effectiveness lasts for eight months.
