Seresto^® combines two active ingredients, imidacloprid (10%) and flumethrin (4.5%). The innovative polymer matrix enables Seresto^® to slowly and continuously release the active ingredients in low concentrations for eight months.

The Seresto^® collar is for use on puppies and dogs 7 weeks of age and older, making it easy to protect dogs from fleas and ticks for eight continuous months. Seresto^® for small dogs is designed for dogs up to 18 lbs. (8 kg); Seresto^® for large dogs is designed for dogs over 18 lbs. (8 kg).

Under normal conditions, effectiveness lasts for eight months. In order to maintain an eight-month duration, dogs must not be bathed more than once per month. For dogs who swim once a month or more, the control duration is reduced to five months for flea control and reduced to seven months for tick control.

Remind your clients to replace the collar after eight months for optimal flea and tick protection.

Seresto^® for small dogs: One display unit contains 6 tins, containing Seresto.

Seresto^® for large dogs: One display unit contains 6 tins, containing Seresto.

Yes. Seresto^® can be used alongside identification or restraining collars without damaging them.

Seresto® kills existing fleas within 24 hours after application. Once Seresto®  has been on your dog for 24 hours, re-infesting fleas are killed within two hours — before they can lay eggs.  

Seresto® begins preventing ticks within 48 hours of application. Re-infesting ticks are repelled and/or killed in as quickly as 6 hours. 

Seresto® does not need to be removed when a dog gets wet or is bathed. The active ingredients are contained in the collar matrix and will not be released into water. They spread through the lipid layer of the dog's skin and hair and even if this lipid layer is partially washed off by bathing, Seresto® will quickly replenish the active ingredients and the dog will be protected again.

However, prolonged, intense exposure to water or extensive shampooing should be avoided as the duration of activity may be reduced. In order to maintain an eight-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 flea control and reduced to seven months for tick control.
