These ingredients work together to provide dual-action protection against parasitic pests for up to eight months!

  • Also repels and kills ticks within 48 hours of initial application and re-infesting ticks within in six hours; works on contact with no painful biting required.
  • Easy-to-use, 27.5-inch adjustable collar is odorless and non-greasy; quick-release feature and visibility reflectors provide extra safety.
  • Water-resistant formula continues working for up to eight months, even after bathing, swimming and sun exposure.



Read the entire label before use. Use only on dogs. Do not let children play with this collar.



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.  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.

    Took about two weeks to not see fleas on my cat anymore but now seems very effective. Has no smell and doesn??t seem to bother him.

    Applied collars to two dogs and one cat. Almost instantaneous relief. I could not be more pleased with this product.

    This is by far the best anti-flea and tick collar (and product in general) I have used for my cat. No problems with his skin and no ticks and fleas!

    We have had this flea collar for 6 months now and it is still working. We havent had any problems with reactions or anything from our cat. We have been very pleased and will buy this again.

    My two black labs suffered for years with me trying product after product after product with little to no relief. My lieutenant at work told me about some collar is he used on his dog, I was skeptical and put off trying it because of the price tag. I wish I hadn??t put it off, they are both flea free and happy!

    Was told of this product by my vet. Was kind of sceptical at first as the old collars that used to be used were not effective at all. However, so far nary a sign of a flea/tick nothing. This collar really works!!

    Wow! For the first year I've had no ticks or fleas. Have had on my long haired husky mix and shorter haired Bichon mix and both have done great. Put them on in April, is now October, still working with no side effects. Would highly recommend. P.s. we live on 16 acres of woods where the dogs run free.

    This is the best flea and tick control for my husky. Take him hiking often and it works for about 6-7 months.

    This is the only flea and tick medicine that seems to work for my dogs. I definitely will continue to buy them.

    Well worth the price. Lasts more than 8 months if your dog is mostly inside and you make sure to take it off before bathing

    Just bought another one after being effective for ticks for 8 months on the dot

    Last summer my dog was infested with fleas and the product I was using stopped working. I bought Seresto and it did the job for the next eight months. When the fleas appeared again I bought another Seresto collar and the problem was solved.
