Important Information

Fleas rise to the top of your pet's coat as they die, so consider it a triumph if you start seeing more fleas at first, after treating your pet. If you’re still seeing fleas after application, it may be because your pet has picked up new fleas from the environment, which may include other pets, surfaces and outdoor areas. It may take up to 30 days to break the entire flea life cycle. Additionally, you should also treat sources of new fleas (i.e., carpet, yard, etc.) to ensure complete flea control.

8-Month Protection for 9 Lives

Give your cat the long-lasting protection of Seresto. This easy-to-use, non-greasy, odorless collar kills and repels fleas and ticks for eight continuous months with proper use, so your feline has protection from these biting pests. Get the performance you expect from a monthly topical treatment in an economical collar for convenient, effective protection against fleas and ticks.

Continuous Release for Long-Lasting Prevention

With Seresto, fleas and ticks are killed through contact, with no biting required. The active ingredients stored within the collar release in low concentration with daily wear and are distributed over your cats skin and coat from head to tail for effective protection. As the active ingredients wear off over time, the collar continuously replenishes the skin and coat with a new supply, for 8 continuous months.

Why Choose Seresto?

The veterinarian-recommended Seresto collar is non-greasy and helps avoid the inconvenience of applying monthly flea and tick treatments. It's easy to adjust for a secure fit and kills and repels ticks too. This is important because if a flea or tick is repelled, it cannot bite and transmit disease. Plus, the collar is designed with a ratchet-release mechanism and pre-determined breaking point.

Is Seresto the Right Choice for your Cat?

If your cat is always on the go or dislikes topical and oral medications, then the Seresto collar is a great option to help keep them protected. The Seresto collar provides pet owners with a convenient flea and tick preventative option that works continuously for eight months, eliminating the need for monthly reapplications.

Protection Your Pet Can Wear

Seresto brings convenience to every pet owner with lasting 8 month protection against fleas and ticks that's totally wearable. Plus, Seresto works through contact which means fleas and ticks don't have to bite for the active ingredients to work. It's also available without a prescription, so it's just one less step to take care of.

how long until all fleas are gone ?
Answer by Chewy • Apr 14, 2023
This collar starts to repel and kill fleas within 24 hours of initial application and re-infesting fleas within two hours. It works on contact with no painful biting required. This collar offers 8 months of protection against fleas and ticks.

Does this Seresto collar also kill flea eggs?
Answer by Chewy • Jul 14, 2017
Seresto kills existing fleas within 24 hours, killing and repelling fleas before they lay eggs.

My cat cuddles with me to sleep and occasionally sleeps on my pillow. Is it okay for her to continue to do so once I put the collar on her? It wouldn’t hurt her or myself?
Answer by Chewy • May 05, 2019
It is safe to allow pets to sleep in bed with you while wearing this collar. The active ingredients spread from the site of direct contact over the skin surface, so it is not recommended to continuously touch the collar.

If my cat is cleaning itself and starts to lock the collar is it bad for them
Answer by Chewy • Aug 09, 2021
When sized properly (snug but loose enough for a finger underneath) the cat will have difficulty licking the collar. The collar is non-toxic but it can cause upset stomach if it were to be licked or bit by your pet. If pieces of the collar were to be ingested it can cause an obstruction so it's best to reach out to a veterinarian and Bayer's medical emergency hotline which is 1-800-422-9874.

Not so effective

My parents introduced me to these several years ago, and they seemed like the only thing on the market that worked without visibly hurting the pets, even ones with health problems. More recently, my husband and I have had problems with collars that simply don't work so well. They never seem to quite get rid of the fleas, and they stop working noticeably several months too soon. Not sure what to do next, because we tried another product and suddenly had a paralyzed pet. Seems like flea treatment, like the fleas themselves, go through a life cycle: they start off great, then stop working entirely or even cause harm.

Worked when nothing else did

Fleas were next level this year! Have one cat and it has not been this bad since 2016. We tried the non-chemical (cedar oil spray, flea traps, etc.) but it only put a dent in the numbers. Frontline does NOT work in Washington state anymore. Wasted the money on those topical treatments. Read positive review from other pet owners in our state and Seresto collars were recommended. Please note: Be ready to deal with an onslaught of fleas jumping ship in the first few days. I thought the collar was not working and then read the product sheet that comes with it and it talks about this. You could tell they were dying, as they were slow and did not jump so were easy to nab. We sprayed everything down with Wondercide cedar oil spray to finish them off. I can say we eradicated the situation within 5-7 days.

Worked amazing until recently

Have been getting these for my cats as they are allergic to fleas and they will lick themselves raw if untreated so I opted to get the expensive " reliable " brand to make sure that they get the protection they need, it worked great for 3 or 4 years and now this recent batch is not working straight out of the tin, could not suggest this brand currently and I will no longer be using chewy for my pets supplies
