Seresto provides long lasting protection against fleas and ticks. It also prevents the flea tapeworm, through its effective control of the host (the cat flea). Seresto also protects against the deadly tick-borne Ehrlichiosis protozoa through effective control of the host (the brown dog tick). Seresto does not protect against other intestinal worms, heartworm, or mites.

Seresto is a collar that is fitted around the neck, providing 8 months of flea protection, and 4 months of tick prevention. For best performance replace the collar on or around the same date every treatment month.
