Seresto

About Seresto

Seresto is a long-lasting flea and tick collar for dogs and cats, manufactured by Elanco (formerly Bayer Animal Health). The range includes collars for small dogs (under 8 kg), large dogs (over 8 kg), and cats. Each collar provides up to eight months of continuous flea and tick protection from a single application, making it one of the longest-lasting parasite treatments available.

Seresto uses a patented polymer matrix that releases imidacloprid and flumethrin in low, controlled doses across the collar's eight-month lifespan. The active ingredients spread across the skin and coat through natural oils, killing fleas and ticks on contact without requiring them to bite first. The collar is water-resistant, odourless, and non-greasy — addressing the common complaints about topical spot-on treatments. The breakaway mechanism on the cat collar adds a safety release if it catches on something.

Australian pet owners choose Seresto for the sheer convenience of eight months of hands-off protection. One collar replaces eight monthly spot-on treatments, which appeals to busy households and owners who struggle to remember monthly parasite prevention schedules.
