The Seresto Collar — Product Review


The Seresto collar provides sustained release technology in an easy-to-apply, odorless, non-greasy collar that keeps them protected for 8 months. It both kills and repels fleas and ticks. The flea or tick does not have to bite your pet to be kept at bay. Therefore, disease transmission (Lyme disease, Rocky Mountain Spotted Fever etc) can be almost eliminated by using this collar. The collar also aids in the treatment and control of Sarcoptic mange and kills lice.

The Seresto collar contains 2 active ingredients: imidacloprid and flumethrin. These are stored within the collar and continuously released in low concentration and are dissipated over your pet’s hair and skin for up to 8 months. The collar also has a breakaway design built in for safety purposes.

In my experience, these collars work well on almost all dogs and cats.

Cat Seresto collar.

There are only a few problems, although not all of them are a direct problem with the collar–more of a problem with environment and management. The Seresto collar is described as water resistant and remains effective following shampooing, swimming or exposure to rain. If you keep reading, you will find that in order to maintain the 8-month duration, they should not be bathed more than once a month and for those that swim more than once a month, duration control is reduced to 7 months for ticks and 5 months for fleas. In my area, it seems to be more like 4-5 months. I usually advise to remove them for bathing or swimming if possible. Dogs that are kenneled together often remove them from each other and dogs that are running loose often lose them among the briars (I’ve only seen problems with a Rat Terrier).

The collar does not seem to work correctly in some breeds in my area (Golden Retrievers).  After 6 weeks of continuous wearing, the owner was still removing ticks. I’ve also had one cat that had a topical reaction that visibly was similar to a chemical burn. As a veterinarian, Bayer Animal Health has provided very good customer service by replacing these problem collars so that I could return the owner’s money to them in order to purchase a different flea/tick product. They have also replaced 2 lost collars (these must be lost within 4 months of purchase and only 1 per lifetime of the pet!)

Small dog Seresto collar.

The only problem I have seen is that some websites have collars that are “knockoff” brands for a cheaper price (the cat with the reaction was purchased like this and not at my clinic!) that are available in other countries and may not work as well as those approved by our federal agencies.

In conclusion, I do like and recommend these collars to my clients. I do warn that if dogs are kenneled together to watch for their removal or swim frequently that they will not likely last the full 8 months.  They are a very easy way to protect your cat, small dog or large dog as they can be applied and basically flea/tick control does not have to be remembered almost every month as with other products.  The cost is usually less in the long run as compared to the cost of either monthly topical or oral tablets.
