Seresto

Seresto collars contain two active ingredients—imidacloprid to target fleas and flumethrin to kill and repel ticks. Similar to topical treatments, these ingredients spread from a point of contact over your dog’s skin and coat, from head to tail, killing fleas within 24 hours and ticks within 48 hours of contact. But whereas topical treatments wear off or wash off over time, Seresto collars deliver a continuous concentration of the active ingredients for 8 months. That sustained, long-lasting protection is what makes Seresto different from prescription oral and topical treatments.

Seresto is made by Elanco, a global leader in animal health, which stands behind the safety profile of Seresto collars and the rigorously reviewed data that supports it. Since 2012, over 25 million Seresto collars have protected cats and dogs across America against the dangers of fleas and ticks.

You can purchase Seresto easy-to-use, 8-month collars for flea and tick protection at Petco online or your neighborhood Petco Pet Care Center. No prescription is required.

Seresto is water-resistant, so there’s no need to remove the collar for swimming or bathing. It remains effective following a shampoo treatment, swimming or after exposure to rain or sunlight.

Seresto collars are formed out of a unique polymer matrix, which contains the active ingredients imidacloprid, which has been used in products for years to control flea infestations, and flumethrin, which effectively kills and repels ticks. Together, these ingredients provide dual action protection against fleas and ticks. No other product has this combination of ingredients.
