A Flea and Tick Collar that Works!

Seresto – designed for excellent mileage

Seresto is a new flea and tick collar from Bayer HealthCare, LLC. It is odorless, narrow, fits well, comes with a break-away safety function, and light reflectors. It prevents and treats ticks and fleas for up to 8 months on dogs and puppies 7 weeks of age and older and cats and kittens 10 weeks and older. Read more and apply for rebates at

The Seresto Collar kills fleas. It repels and kills ticks. It is water-resistant* and comes in three sizes: cat, small dog up to 18 pounds, and large dog.

Important Note for Pets in Florida:

If you bath your pet more than once a month, replace Seresto after 5 months.

*Seresto is water-resistant and remains effective following a shampoo treatment, swimming or after exposure to rain or sunlight. Under normal conditions, effectiveness lasts for 8 months. In order to maintain an eight-month duration, dogs must not be bathed more than once per month. For dogs that swim once a month or more, the control duration is reduced to 5 months. (from the Seresto product brochure S13007)

Dependability driven by two active ingredients

The two active ingredients in Seresto are imidacloprid and flumethrin. They are part of the collar’s patented technology. No other treatment has this combination of ingredients. The Bayer Polymer Matrix of the collar is designed to slowly and continuously release the active ingredients over eight months, which makes this collar completely unique among collars. As the active ingredients wear off over time, the polymer matrix of the collar releases just enough medicine to equilibrate with the medicine on the skin to keep uninterrupted protection for 8 months.

If your dog or cat is not used to collars

Please observe your pet carefully when it’s wearing the collar for the first few days. Try using a tasty treat, toy, or other activity to distract your pet’s attention away from the new collar. Occasionally, slight itching may be observed in the first few days of fitting in cats that are not used to wearing collars. Ensure the collar is not fitted too tightly.

    Thanks to Doc Truli, I discovered the Seresto collars for my kitties (other common remedies like Frontline left a bald patch on one of my cats). The collars combined with Doc Truli’s expert advice on how to rid my house of pesky fleas (without using harmful chemicals) during a house call vet visit, the fleas were gone in no time. Thankfully I have never had a problem with them since!
