 The Seresto Flea & Tick collar from Bayer offers a breakthrough of eight months of flea and tick protection for dogs or cats, setting it apart from conventional flea and tick collars.The Seresto collar is designed in such a way as to safely remain in place for up to 8 months, without endangering the life of the animal.
   Seresto is a unique product on the market, it contains a powerful insecticide - imidacloprid and highly effective acaricide - flumethrin. These compounds are incorporated into a polymer matrix used in the construction of the innovative collar waterproof and odorless, so that the active ingredients are all the time - for up to 8 months - released in a suitable low but effective dosage. Its sustained release technology means that the active ingredients are slowly and continuously released over 8 months.
   Kills fleas and continues to prevent re-infestations for up to 8 month. The Seresto collar also repels and kills ticks. The Seresto collar is also water resistant and remains effective following monthly bathing, occasional swimming (if swimming occurs more often than once a month, the duration is reduced to five months) or after exposure to rain or sunshine.
   This collar also features a release mechanism which in the unlikely event of a pet becoming trapped, the pet's own strength is sufficient to allow for a quick release.

For external use only.
Remove collar from protective bag directly before use. Unroll collar and make sure that there are no remnants from the plastic connectors inside the collar. Adjust the collar around the animal’s neck without tightening it too tight (as a guide, it should be possible to insert 2 fingers between the collar and the neck). Pull excess collar through the loop and cut off any excess length extending beyond 2 cm.
The collar should be worn continuously for the 8 month protection period and should be removed after the treatment period. Check periodically and adjust fit if necessary, especially when puppies and kittens are rapidly growing.

For the treatment of dogs over 7 weeks of age.

For the treatment and prevention of flea (Ctenocephalides felis) infestation for 7 to 8 months, and as part of a treatment strategy for the control of Flea Allergy Dermatitis (FAD). Efficacy against fleas starts immediately after application of the collar.

Amazing product

We have 5 animals 3 have extreme allergies to fleas. I have tried everything nothing helped them until I stumbled on Soresto. My animals have complete relief for 8 months then we replace. Forests is the same thing. Yes it is expensive but if you tally it up it’s less expensive in the long run. How much do you pay for your meds that have to be administered once a month? Do yourself and your animals a favor!


Only took 40 days or so to get. Tracking number for the first 35 days was useless.

Worked for one and not for another

I purchased two of these collars for 2 of my dogs. One dog has 0 ticks or fleas the other in the exact same area has a bad infestation. Both collars were in date and are tightened to recommended specs.

I am glad

My dog looks happy than I am happy:- ) I am going to buy it every season.

No Reflectors included

These are really great tick/flea collars, identical to the Soresto brand sold in the USA...except for one difference: Soresto collars each come with three snap-on reflectors. They are pretty high quality reflectors that light up brilliantly when hit with a car's headlight, or any other light. Major safety benefit. The Foresto collars sold by EAS DO NOT come with reflectors. Interestingly, the English instructions EAS supplies (the ones on and in the product are in Polish), do refer to the reflectors, and how to properly attach them to the collar.
EAS should make clear on their site that the Foresto collars they sell come minus the reflectors. As of today (3/19/2017) their pages for Foresto products do not list this difference.
