Our take on the Bayer Seresto Flea and Tick Collar for Dogs, 8-Month Protection

The Seresto collar is a slow-release flea and tick collar for large dogs, using imidacloprid and flumethrin to kill fleas within 24 hours and reinfesting ticks in as little as six hours. One collar is worn continuously for eight months, which makes it cheaper per month than most spot-on treatments. The best new price is $29.99 at eBay as of November 4, 2026, with two stores listing it new.
