Seresto Flea and Tick Control Collar

Fleas and ticks do more than just bite. They can also transmit diseases, which can be harmful and even fatal for pets.

Only Seresto flea and tick control collar protects your dog for up to 8 months in a single application. The collar releases its active ingredients at a slow and steady rate, and is able to kill fleas and repel and kill ticks without the need to bite your pet.*

Just pop it on your dog for up to 8 months of protection. No mess, no grease, no smell - and no need to remember monthly flea and tick applications.

How Seresto Flea and Tick Collars Work

Seresto Collars have been made with a unique polymer matrix of two active ingredients that work in synergy to target all fleas and ticks. Over a period of up to 8 months, these active ingredients are released in low concentrations onto you pet's skin and hair, which are then distributed over the entire body surface to offer long-lasting protection.

How to Fit the Seresto Collar

Use only one collar per animal. Carefully wrap the collar around your dog's neck and push the leading end through the loop, allowing for 2 fingers to fit between the collar and neck for a comfortable but snug fit. Cut off excess length past 2cm.

The collar should be worn continuously for the up to 8 month protection period and should be removed after the treatment period. Check regularly and adjust if necessary especially when puppies are rapidly growing.
Do not use on puppies less than 7 weeks of age.

Please read all product packaging before use.


I have never had a flea problem before. Where are my pets picking up fleas?

Fleas are very hardy pests. Your pet is potentially exposed to fleas every time they step outside your house, especially in areas where there are other animals. As stray or homeless animals are not being cared for, even a single feral cat passing through your garden can leave behind flea eggs that are then picked up by your cat or dog. Fleas may also be brought into the house through clothing, luggage, or non-treated pets in your neighbourhood.

What are the benefits of Seresto?

Seresto's unique polymer matrix contains two active ingredients:

Imidacloprid controls flea infestations
Flumethrin effectively repels and kills ticks

The active ingredients spread from the site of direct contact over the skin surface, and are continuously replenished in low concentrations as they wear off over time. Bayer's unique polymer matrix technology means the active ingredients remain effective for up to eight months, a duration that makes it clearly different from other flea and tick collars.

How quickly will the collar begin working?

Seresto kills existing fleas on dogs within 24 hours after application. Once Seresto has been on your dog for 24 hours, re-infesting fleas are killed within two hours. Infestation prevention with new ticks starts within 48 hours after Seresto collar application. Re-infesting ticks are repelled and/or killed in as quickly as 6 hours.

Is Seresto water resistant?

Seresto is water resistant. It is unnecessary to remove the collar before your dog is immersed in water because Seresto remains effective following a shampoo treatment, swimming, or after exposure to rain or sunlight. In order to maintain an 8-month duration, dogs must not be bathed more than once per month. For dogs that swim once a month or more, the control duration is reduced to five months for fleas and seven months for ticks.

What if my dog gets stuck while wearing a Seresto collar?

Seresto is designed with a safety release mechanism. In the unlikely event your dog becomes trapped, its own strength is sufficient to widen the collar and allow for a quick release. Seresto collars for small dogs are also equipped with a predetermined breaking point, so a harder pull will trigger the breaking of the collar.

When can I bathe my dog after application for Seresto for dogs?

We recommend bathing BEFORE applying product. The product can be applied once the pet is towel dried. There is no need to remove the collar for bathing. Please use a non-stripping, pet shampoo.

How do I store and dispose of Seresto?

Store in the original unopened container in a cool, dry place inaccessible to children.
Dispose of container, pouch and expired collar in the bin.
