What is Seresto?

Seresto is an effective, reliable alternative to monthly flea and tick topicals. This dual-action collar repels and kills fleas & ticks for 8 consecutive months. If a flea or tick is repelled, it cannot attach and transmit disease-causing organisms. Seresto is a flea and tick collar for dogs and cats that uses exciting, innovative technology to release the active ingredients in controlled doses over an extended period of time. This means effective long-term flea and tick control without the inconvenience of monthly applications. Seresto protects your pet from fleas, flea eggs, flea larvae, ticks, as well as sarcoptic mange on dogs without odor or mess. It is available in three formulations for small dogs, large dogs, and cats.

Please Note: We cannot ship this product to Canada.

For:

Dogs (7 weeks of age or older), Cats (10 weeks of age or older)

Benefits:
  • Begins working immediately after the collar is applied
  • Repels and kills fleas & ticks for 8 months, helping to prevent attachment and subsequent transmission of disease-causing organisms.
  • Kills fleas before they can lay eggs
  • Prevents tick infestations within 48 hours after application
  • Aids in the control of sarcoptic mange on dogs
  • Water-resistant and will continue to work even if wet or dirty
  • Odor-free compared to older-generation flea and tick collars
  • Non-greasy, odorless, convenient.
  • Safety release mechanism prevents strangulation if the collar becomes caught or tangled
  • Safe if chewed on by your dog or cat
  • Light reflectors for added visibility in the evening and at night
How it Works:

The flea and tick collar releases the two active ingredients in low doses over an extended period of time. The ingredients are then absorbed through the fatty layer of your pet's skin and distributed throughout your pet's body to protect against fleas and ticks for eight months. Seresto can be worn alongside your pet's regular collar. No matter if you have a cat or a dog, the collars come with a ratchet release mechanism that releases when your pet is under pressure, which enables your pet to free himself or herself. It also has a pre-determined breaking point if your pet's head and neck get trapped, which allows your pet's strength to break the collar and get out of a dangerous situation.

Cautions:

The collar should not be used on puppies younger than seven weeks old or on kittens younger than ten weeks old. If ticks are present on your pet when the collar is applied, they will not die within the first forty-eight hours and should be removed manually. If your dog or cat shows any sign of skin irritation or other reaction to the collar, remove immediately and consult your veterinarian.

Seresto is rated 3.6897 out of 5 by 290.
Rated 5 out of 5 by from Works fast and completely effective! I put the collar on my two dogs 7 days ago. I have a small dog and medium dog (5 and 34 lbs). Both were picking up fleas from our walks in the neighborhood. After I shampooed them and placed the collar on them no more fleas! I had shampooed them before and used other products and a day later they would have fleas. We go for walks in the same areas and no more fleas. Neither has had any reactions to the collar. I am extremely happy with the Seresto collar and so are my dogs.

Rated 5 out of 5 by from Effective but wish it was waterproof I bought this a couple months ago and so far I have seen great results. I wish it was waterproof, but will take it off my dog when he gets wet. My dog itched the first week or so (just like the instructions said might happen) but since then we have seen no issues. Would love to see a waterproof one, but I'm happy that I don't have to remember a monthly dose, or put chemicals on his fur.

Rated 5 out of 5 by from Works Great! So far the product does exactly what it says it does. Great for my indoor dogs. We live on a farm. Put it on my big outdoor dogs and they lost the collars within two days from playing with each other in the woods. Great not to have prescription.

Rated 1 out of 5 by from Did not work!!! Bought this about three months ago for my little dog and big cat and it only worked about a month!! Was super bummed total waste of money!!

Rated 4 out of 5 by from Great but watch out for water! Got two of these for my sheps. Both go out with me hiking and to the hunting ranch. The hogs have terrible fleas out there and both sheps got infested. They were running through the grass and ended up in a bed. Put these collars on them and it killed all the fleas in my house and on them for about 3 months. Took them outside in the rain and it ruined the collars. The got small fleas again from hiking. The product is great but make sure to take it off when your dog might get wet. I usually throw them in my bag when we're near water and then put them back on once they dry off. Four stars instead of five because they aren't water proof at all.

Rated 1 out of 5 by from Does not work! I bought this collar for 2 dogs that stay outside. I had used Frontline or Advantage on a monthly basis for years but it doesn't work anymore. Seresto is pricey but I thought it would be worth it if it worked for 8 months. Big mistake! The collars have been on for a week and there has been zero reduction in fleas on the dogs. Very disappointed in this product.

Rated 5 out of 5 by from Perfect solution! This is my third flea season with the collar. My 9 year-old beagle is nerdy allergic to just about everything...especially fleas. For years, she did fine with prescription treatments, but they all stopped working. I tried everything to keep her from ripping her fur out in order to dig at the skin rashes. She was miserable! I took her to another vet who recommended the Seresto collar along with steroids and antibiotics. Within a few days, the itching subsided. Within a week, the itching was gone. Within a month, my house was flea free and her fur was growing back! I only keep it on her during the warmer months and replace it at the first sign of spring itchies. (She's an in-door doggie...only goes outside to potty and to the park for play time.) So far, so good! Excellent product!!! Thank you! Thank you! Thank you!

Rated 2 out of 5 by from Not working Have had this product for over a month of my dog who has medium length hair. It isn't working and this was supposed to be my last hope. For some reason it is working for my boyfriends dogs. Maybe I got a bum one? Would love a refund or a new one to be sent.

Can you use frontline plus as well?

It is not necessary to use Frontline Plus in conjunction with the Seresto collar. This may over medicate your furry baby.
