How do I know if the Seresto collar I purchased is authentic?

It is crucial that pet owners purchase real and genuine Seresto products from authorized and trusted retailers. Counterfeit collars and their packaging look very similar to the actual product. Be sure the collar does not have a greasy feel or an odor.

Does it expire?

There is no expiration date required on the packaging.

The product should be kept in its original packaging and stored as directed on the label.

What are the key ingredients?

The active ingredients in Seresto collars are Imidacloprid and Flumethrin: Imidacloprid to help protect against fleas and Flumethrin to help protect against ticks. No other product has this combination of ingredients.

Important Information

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.
