Your Pet Is Our Top Priority

At Elanco, the health and well-being of your pet is our top concern with any of our products, including Seresto®. Not only did we thoroughly test Seresto, including its active ingredients and collar components, as part of its development for registration in the U.S. and approval globally, but we closely monitor Seresto continuously to ensure its performance. Since initial EPA registration in 2012, over 25 million Seresto collars have protected pets in the United States from fleas and ticks.

Systemic vs. nonsystemic protection

With oral preventives, active ingredients are ingested into the bloodstream and require fleas and ticks to bite to die. But the nonsystemic protection of Seresto® distributes them across the coat and skin — so fleas and ticks don’t have to bite your pet to die.

Top questions about Seresto®

How do Seresto® collars for dogs work?

The Seresto® collar works with a unique polymer matrix of two active ingredients, which spread from the site of direct contact over the skin surface of your dog:

  • Imidacloprid has been used in products for years to control flea infestations.
  • Flumethrin effectively kills and repels ticks.
  • Flumethrin works together with imidacloprid to provide dual action against fleas and ticks. No other product has this combination of ingredients.

Sustained release technology

Seresto® works similarly to a monthly topical in the fact that the active ingredients spread from the site of direct contact over the skin surface. The active ingredients in Seresto® are released in low concentrations from within the collar and, thanks to your pet's skin and coat, spread from head to toes, even the tail. As the active ingredients wear off over time, a new supply is continuously replenished in low concentrations for 8 months. The long-lasting, 8-month duration of Seresto® differentiates it from other flea and tick collars.

Do Seresto® collars for dogs expire?

There is no expiration date required on the packaging by the EPA for Seresto® for dogs. The product should be kept in its original packaging and stored as directed on the label.

Can I bathe my dog with the Seresto® collar on?

Seresto® is water-resistant and remains effective following a shampoo treatment, swimming or after exposure to rain or sunlight. Under normal conditions, effectiveness lasts for 8 months. To maintain an 8-month duration, dogs must not be bathed more than once per month. There is no need to remove the collar for bathing. Please use a gentle, soap-free pet shampoo.

How do I apply the Seresto® collar and take it off my dog?

How to apply the Seresto® collar on your dog:

  1. Remove the collar from its packaging.
  2. Unroll the collar and remove the small plastic connectors from inside the collar, ensuring that no remnants remain.
  3. Insert the end of the collar through the buckle and loops.
  4. Adjust the collar around your dog's neck until it fits comfortably on them.
  5. Two fingers should fit beneath the collar and neck to ensure it's not too tight. Any excess length of the collar beyond an inch past the loops should be cut off, unless it is on a growing puppy, where some additional length may be needed for adjustment as the puppy grows.
  6. Check periodically and adjust fit if necessary, especially on growing puppies.
  7. Seresto® comes with three optional reflector clips that can be attached to the collar to help keep your dog visible at night. The reflector clips should be evenly distributed on the non-overlapping part of the collar.

Watch our application video for more information.

How to take the Seresto® collar off your dog:

Squeeze the outer sides of the buckle while pulling from the other end or side of the collar. Some may find it just as easy to cut the collar off before applying the new Seresto® collar.

Why can Seresto® be used on pets?

Seresto® kills fleas and ticks.

Seresto® was designed with specific ingredients at doses that are active against fleas and ticks. Studies show that fleas and ticks are highly susceptible to the combination of imidacloprid and flumethrin found in Seresto®.

The Seresto® collar works with a unique polymer matrix of two active ingredients, which spread from the site of direct contact over the skin surface of your dog. The active ingredients in Seresto® are released in low concentrations from within the collar. As the active ingredients wear off over time, a new supply is continuously replenished in low concentrations. Imidacloprid has been used in products for years to control flea infestations. Flumethrin effectively kills and repels ticks.

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

It’s crucial that pet owners purchase real and genuine Seresto® products from authorized veterinary clinics and trusted retailers to help ensure product authenticity and performance. Find Seresto® at a clinic or retailer online or near you.

Is there a Seresto® recall?

There is no evidence in the scientific evaluation conducted for registration or the regularly reviewed pharmacovigilance data to suggest a recall of Seresto® is warranted, nor has one been requested, or even suggested by any regulatory agency. As a result, Elanco continues to stand behind the safety profile of Seresto®. It remains available to consumers as an effective way to protect pets against fleas and ticks that can transmit disease and can impact their quality of life.
