Product Detail: Seresto


Seresto is different from conventional flea and tick collars. It employs a novel blend of materials, enabling a safe, controlled, low-dose release of active ingredients over 8 months. This provides excellent protection for your pets, not only killing fleas and ticks but also repelling ticks before they bite, helping to protect your pet from the diseases these parasites can spread.


What are the active ingredients in Seresto?

Active ingredients: 


How Seresto works

The Bayer Polymer Matrix System ensures that both active ingredients are slowly and continuously released in low concentrations from the collar towards the animal. This avoids peak concentrations and ensures that concentrations of both active ingredients are present in the pet's haircoat during the entire efficacy period. The active ingredients spread from the site of direct contact over the entire skin surface.


Is Seresto still effective after giving your pet a bath?

Seresto is water-resistant and remains effective following a shampoo treatment, swimming, or after exposure to rain or sunlight. 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.

Under normal conditions, effectiveness lasts for 8 months. In order to maintain an eight-month duration, dogs must be bathed more than once per month. For dogs that swim once a month or more, the control duration is reduced to 5 months for flea control and reduced to 7 months for tick control. There is no need to remove the collar for bathing. Please use a non-stripping, pet shampoo.

After losing a perfectly healthy dog to a flea and tick oral medication I was scared to try any other pills. I was concerned about the price of these collars but they are definitely worth it! I get them for all of my dogs before spring and never have any problems. I have taken my dogs on various walks and don't have to worry about what might crawl on them because it will not stay. I have taken them through yards that I later found out were flea and tick infested, my dog's came out without a single flea or tick on them. If for some reason your dog has a reaction to these collars you are not trapped in the same type of situation as you would be if your dog has a reaction to an oral medication or one of the waterproof topicals. If I could give these collars a higher rating than five stars, I would.

We buy these collars for our dogs every 8 months. They are worth every dollar. What other products on the market works for 8 months non stop. This collar saved my boyfriend's Yorkie. He had used several brand name medications plus antibiotics, but he was suffering terribly with fleas. I suggested he try these collars and he did. Wow, this collar literally saved his little Yorkie's life. I'm so grateful for this great product.
