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.

Active Ingredients: Flumethrin 4.5%, Imidacloprid 10.0%.
Use only one collar per animal. Fit collar around your pet's neck, allowing for 2 fingers to fit between the collar and your pet's neck to ensure a comfortable, yet snug, fit. Once collar is properly fitted, cut off any excess collar measuring 1" or longer. The collar should be worn continuously for the 8 month protection period. Check periodically and adjust fit if necessary, especially when puppies are rapidly growing. Keep the collar in the bag and in the outer packaging until use. Replace the collar after 8 months for optimal tick and flea protection.
Water Resistance: It is unnecessary to remove the collar before immersing your pet in water. Seresto remains effective following a shampoo treatment, swimming or exposure to rain or sunlight. In order to maintain an 8 month duration, pets must not be bathed more than once a month. For pets that swim once a month or more, the control duration is reduced to five months for fleas and seven months for ticks.

I have never had a flea problem before. Where are my pets picking up fleas?
Fleas are very hardy pests that are quite capable of hitching rides on a variety of mammals. Wild animals or feral pets traveling through the environment may be a source for a pet’s exposure.Fleas may be brought to the house by: * You – attached to clothing, luggage, dog blankets, etc. * Your pet – any time your pet steps outside your house, they are potentially exposed to fleas, especially in areas where there are other animals. * Stray or homeless cats and dogs – since these animals are not being cared for, they are easy targets for fleas. A single feral cat walking through your backyard even just one time may drop many flea eggs into the grass or under shrubs. * Wildlife – particularly raccoons and opossums. These animals typically aren’t seen very often, because they are active at night. A single opossum can carry as many as 1,000 adult fleas! An opossum walking through your backyard even just one time can drop many flea eggs into the grass or under shrubs as they pass through. * Non-treated pets in the household – most dogs are treated for fleas and ticks. Often, the cats in the household are not, especially if they are indoor only cats. * Non-treated pets in the neighborhood – you may be vigilant about treating your pets for fleas, but your neighbor(s) may not.
What are the benefits of Seresto?
Inside the unique polymer matrix of Seresto are two active ingredients:
-
Imidacloprid has been used in products for years to control flea infestations.
-
Flumethrin effectively repels and kills ticks.Flumethrin works together with imidacloprid to provide dual action against fleas and ticks. No other treatment has this combination of ingredients.The active ingredients spread from the site of direct contact over the skin surface of the cat or dog.Sustained release technologySeresto works similarly to a monthly topical, but as the active ingredients wear off over time, a new supply is continuously replenished in low concentrations. The active ingredients spread from the site of direct contact over the skin surface.Bayer's polymer matrix technology is designed to slowly and continuously release the active ingredients for eight months, a duration that makes it clearly different from other flea and tick collars.
Is Seresto water resistant?
Seresto is water resistant. The active ingredients of Seresto are contained within the Bayer Polymer Matrix, making it water-resistant. Therefore it is unnecessary to remove the collar before the pet is immersed in water. Seresto remains effective following a shampoo treatment, swimming, or after exposure to rain or sunlight. Under normal conditions, effectiveness lasts for eight months. In order to maintain an 8-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 five months for fleas and seven months for ticks.
What if my cat or small dog gets stuck while wearing a Seresto collar?
Because some pet owners may be concerned that a cat or small dog could get stuck while wearing a collar, Seresto is designed with a safety release mechanism. In the unlikely event of the cat being trapped, the cat's own strength is sufficient to widen the collar to allow for quick release.A hard pull causes the ratchet-release mechanism to allow a widening of the collar.The small dog and cat collars are equipped with a predetermined breaking point. A harder pull triggers the breaking of the collar at this point.
What is the expiration date for Seresto for dogs?
There is no expiration date required on the packaging by the EPA for this product. The product should be kept in its original packaging and stored as directed on the label.
When can I bathe my dog after application of Seresto for dogs?

So disappointed in Seresto this year
By AmyJ on Jun 9, 2021
My dog and cats have had Seresto collars each summer since 2016. I have been to over 4 seminars held by Bayer to learn more about the pesticides, how to use these etc. Let's just say after 14 years in the veterinary industry I'm no amateur to the products available or how to use them properly and believed this was the one. We are avid campers and hikers and need our 11 yr old dog to be protected as we live in a very tick prone area. Our first camping trip was 2 weeks ago. 4 days later when we returned home we started finding giant blood filled ticks that had fallen off of our dog. I believed them to be dead so figured it was okay. This morning was the last straw. My dog had been chewing on her My dog and cats have had Seresto collars each summer since 2016.

I believed them to be dead so figured it was okay. This morning was the last straw. My dog had been chewing on her toes and when I looked .. each toe had a tick in between. They were fat as can be, nasty little wiggly legs and weren't dead AT ALL. So Seresto did NOTHING to protect her from over 8 ticks we found. I have thrown the collar away and will be finding new protection for all of our pets. I'll spend the day combing through our dog's fur to make sure she doesn't have more ticks hidden. I spent over $100 for these to do nothing and to just throw them away. I am not pleased with Seresto or their maker and will no longer support the company. … more

Worked great last year! Not so much now.
By ElliesMom on Jun 8, 2021
I was super pleased with this product last year when I got it for my shepherd. It worked great although I did find the occasional tick on her. However, this year I’m pulling multiple ticks off of her nearly every day. My poor dog has scabs all over her body from having so many ticks on her with the majority of them still being alive when I find them. I did hear that this product can become defective if your dog is an active swimmer, but that’s not my dog. I’m very disappointed with the performance of this product this year. I just gave in and purchased a different flea and tick treatment even though I was anticipating that this collar would last me throughout the summer.

Not good. Covered in ticks
By Megan on Jun 3, 2021
I have used Seresto before and used to recommend it as a groomer to all of my clients. However, the last Seresto I purchased a little over a month ago was completely ineffective. I have found ticks on my dog that have been clearly feeding for several days and they are completely alive and well, As compared to only finding small dead ones before with previous seresto collars. This is a huge disappointment. Back to Bravecto for me

Must be returned
By KKell on Jun 10, 2021
I bought 2 of these collars after calling Chewy to double check on sizing. They stated these were correct size for my 2 dogs. Not correct. Im not happy as they are way way too large. I believe information I was given was incorrect- and now need to return both collars. They are very expensive as well. Cant comment on if they work as they do not fit my dogs.

Bayer sold Seresto
By Natasha on May 29, 2021
THIS REVIEW IS REGARDING SERESTO ONLY AND IS NOT A REFLECTION OF CHEWY’S CUSTOMER SERVICE. Chewy is great! Love them! However, we’ve been using Seresto collars for years and they have always worked wonderfully. This time, unfortunately, they are not repelling or killing ticks. We live right up against the woods, so my dog has been coming home absolutely covered in ticks. No good. Through a little research, I discovered that Bayer sold its Animal Health Division, including the Seresto brand, to a company named Elanco. When one company “sells out” to another, there’s always a decline in quality, and in this case, our animals are left paying the price.

This works for my pet family
By Lisa on May 20, 2021
I have used this product for years. I have never had a problem with fleas or ticks after using Seresto on my dogs. I have indoor cats, with no flea or tick protections & they never have fleas or ticks either. So this product protects my dogs and my indoor cats. Plus if I choose to remove it, for whatever reason I can. The last time is used a flea and tick topical ointment for my dogs they had a bad allergic reaction, after that I started using Seresto with never any issues.

Not working this year
By Grecia on Jun 7, 2021
I purchased this product for the second time this year. My dog really suffers from flea bites from spring and summer. Last year we invested in this collar and it seemed to work just fine, so we ordered it again this year. It does not seem to be doing it’s job this time around. My dog is full of bites and really suffering. Will look into an alternative.

ineffective
By Cali on Jun 7, 2021
We usually use the soresto collar for our dogs every year and it works beautifully as we live in a heavily wooded area but this year it seems that every time my dogs come inside I am finding ticks on them, most of the time embedded. Not sure what’s going on this year but I’ve seen many other similar reviews! Probably going to switch back to nexgard.

Great product and great customer service!
By Rosa on May 16, 2021
I have been purchasing this product from Chewy for a few years and we have been more than satisfied. No fleas, no fleas, no fleas! When ordering I hit the wrong button and signed up for auto ship.. not a good idea for a flea collar. They refunded the charge and let me keep the extra since it came that quick! Normally I would have kept the extra for our other pooch who sadly just went to dog heaven , so I shared with another pooch in our extended family of dog lovers! Chewy, thank you !!

Effective and Affordable!
By CanineSpeak on May 19, 2021
This spring has been horrid for ticks! After pulling nearly a dozen ticks off my dogs in a matter of a week, enough was enough. After purchasing the collars, I no longer find ticks imbedded in my dogs, and I feel more at ease when I take them on walks where there is tall grass. I love that my water-loving Border Collie can enjoy splashing around without me having to remove the collar. In addition, the cost is a big factor. I am happy with the price.
