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.

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.
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 technology*Seresto 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.
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.
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.
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.

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.
So I was a little skeptical about these collars before I purchased them. I had read some reviews online and they were very back and forth, but I decided to go for it anyway! I live in Southeastern North Carolina, and the fleas and ticks rear their heads a lot earlier in the year, so I thought I'd get a head start. The first few days of my dogs wearing the collars, I was tempted to just take them off because it seemed like it was making them itch MORE. I then realized they aren't used to wearing collars at all (we are a harness house for outdoor activities) so I gave it a few more days and I am so glad we stuck it out! The dogs have been wearing the collars for about 2 weeks, and the difference is dramatic. No fleas anywhere, and the dogs are so much more comfortable. Glad I already turned the autoship on so I don't even have to worry when its time to reorder!
This product does what it says it will do but if your dog is allergic then things can be really bad. 1 of 5 had a major reaction. The issues were resolved quickly after removal. There are some serious allergic/sensitivity reactions that must be observed. This product has been known to cause death and life-threatening reactions. We were aware and prepared. I would recommend this product only with customers who can and do monitor their animals the first 24 to 48 hours.
I have been using these since my two German Shepherds were puppies (now 6 years old). Simply put them on loose enough to whereas they will just lay and touch the fur **NEVER put these on tightly!!** So many people complain they have problems with rashes and these don't work for them, many cases I chuck this up to consumer error!! The collars naturally release over the 8 months simply by touching the animals fur. I feel as though they are a great product, give them a try!
This is my favorite flea and tick option for many reasons. My dogs do not reactive negatively to them in any way. I have never seen a flea on them and the only ticks I have seen were ones that had just crawled on them during a hike or were dead. I believe they do not prevent the ticks from biting them, but they kill them after they do. I wish that it did a better job at repelling them all together. We have been using these collars with out 2 dogs for 3 years now. I buy new ones when the weather starts to warm up and just keep them on through the winter. So 12 months, not 8 months (but they are at their strongest during peak seasons)
Within days of putting this on my dog (Moose, Great Dane) we noticed a red spot. Once we noticed this we took it off immediately and took pictures and cleaned him up. It was put on 2-3 fingers loose like instructions say. I will never put another seresto brand on my dogs again.
This Seresto collar is the way to go. We live in an area where ticks are plentiful. And our dogs love to chase and catch rabbits. This is an amazing protection collar. We generally take it off of them when they swim to prolong the life of the collar. And ‘Chewy’ is an amazing company to offer auto ship. And if I have any problems or questions about my order, they are very prompt to reply and assist. I tell my friends that have pets to utilize Chewy. Love it!
I noticed it is not Bayer anymore, my previously was from Europe. I washed my dog with flea shampoo and put this new Elanco collar. After 4 days I still do not see result, my dogs still itching, and I see fleas still when I brush him with fleas comb. I know every one is different and maybe it is dog personal things, we will continue use it but I doubt it is same as used be.
I switched one of my dogs to the collar after he had a horrible attack of pancreatitis after his 2nd dose (ever) of Nexguard -- we had switched after many years of using FrontlinePlus which was losing it's potency. Not 100% sure the Nexguard triggered the pancreatitis, but definitely a possibility given it came on one day later and was the only odd thing he ingested. Don't love the fact he must wear an extra collar nonstop, but it has no odor and seemed to do the trick (no sign of fleas or ticks). Only just learned it does NOT protect 8 months against ticks (only 4 months for those), so will need to swap it out more frequently then I thought. Oh, and also the glow in the dark clips don't work (plus I figured they might rub against his neck too much, but they never glowed in the dark anyway). It also stays put once I put it on him, never came off (unless I took it off) in 8 months. They shouldn't get away with the "8 month protection" blurb the front of the tin, however, given that only applies to fleas.
we have used these collars for several years now and love them. They keep all fleas off our dogs and kill all ticks that we find. We actually keep them on all year since we live in a mild climate. We change them every March to make sure to be strongest for tick season. They still keep fleas gone all 12 months.
I've been using these collars for a few years now. We hike in the woods and fields with our dogs every day and ticks are a real problem in southern Ohio. They come home each day without a tick or flea on them! It couldn't be any easier and no more liquid on me or them every month-I hated that!
