How Seresto® works
See for yourself how Seresto® provides your dog or cat with
continuous protection against fleas and ticks for eight months.
Repelling ticks is key

Ticks can transmit the organisms that may cause diseases. Seresto® repels most ticks
before they can attach.1 If a tick is repelled or killed, it can't transmit the organisms that
cause disease.

Common tick-transmitted diseases include: anaplasmosis, Rocky Mountain spotted
fever, ehrlichiosis, Lyme disease and Cytauxzoonosis.
