Use only one collar per animal. Fit collar around your pet's neck, allowing for 2 fingers to fit between the collar and your pet's neck to ensure a comfortable, yet snug, fit. Once collar is properly fitted, cut off any excess collar measuring 1" or longer. The collar should be worn continuously for the 8 month protection period. Check periodically and adjust fit if necessary, especially when puppies are rapidly growing. Keep the collar in the bag and in the outer packaging until use. Replace the collar after 8 months for optimal tick and flea protection.
Water Resistance: It is unnecessary to remove the collar before immersing your pet in water. Seresto remains effective following a shampoo treatment, swimming or exposure to rain or sunlight. In order to maintain an 8 month duration, pets must not be bathed more than once a month. For pets that swim once a month or more, the control duration is reduced to five months for fleas and seven months for ticks.
Frequently Asked Questions
I have never had a flea problem before. Where are my pets picking up fleas?
Fleas are very hardy pests that are quite capable of hitching rides on a variety of mammals. Wild animals or feral pets traveling through the environment may be a source for a pet’s exposure.
Fleas may be brought to the house by:
- You – attached to clothing, luggage, dog blankets, etc.
- Your pet – any time your pet steps outside your house, they are potentially exposed to fleas, especially in areas where there are other animals.
- Stray or homeless cats and dogs – since these animals are not being cared for, they are easy targets for fleas. A single feral cat walking through your back yard even just one time may drop many flea eggs into the grass or under shrubs.
- Wildlife – particularly raccoons and opossums. These animals typically aren’t seen very often, because they are active at night. A single opossum can carry as many as 1,000 adult fleas! An opossum walking through your back yard even just one time can drop many flea eggs into the grass or under shrubs as they pass through.
- Non-treated pets in the household – most dogs are treated for fleas and ticks. Often, the cats in the household are not, especially if they are indoor only cats.
- Non-treated pets in the neighborhood – you may be vigilant about treating your pets for fleas, but your neighbor(s) may not.
What are the benefits of Seresto?
With its innovative delivery system, Seresto offers a breakthrough in flea and tick protection for dogs or cats for eight months.
Features and benefits:
- For dogs or cats
- Kills fleas
- Repels and kills ticks. If a tick is repelled, it cannot attach and transmit disease-causing organisms
- Non-greasy, odorless, easy-to-use
How does Seresto work?
Inside the unique polymer matrix of Seresto are two active ingredients:
- Imidacloprid has been used in products for years to control flea infestations.
- Flumethrin effectively repels and kills ticks.
Flumethrin works together with imidacloprid to provide dual action against fleas and ticks. No other treatment has this combination of ingredients.
The active ingredients spread from the site of direct contact over the skin surface of the cat or dog.
Sustained release technology
Seresto works similarly to a monthly topical, but as the active ingredients wear off over time, a new supply is continuously replenished in low concentrations. The active ingredients spread from the site of direct contact over the skin surface.
Bayer's polymer matrix technology is designed to slowly and continuously release the active ingredients for eight months, a duration that makes it clearly different from other flea and tick collars.
What if my cat or small dog gets stuck while wearing a Seresto collar?
Because some pet owners may be concerned that a cat or small dog could get stuck while wearing a collar, Seresto is designed with a safety release mechanism. In the unlikely event of the cat being trapped, the cat's own strength is sufficient to widen the collar to allow for quick release.
A hard pull causes the ratchet-release mechanism to allow a widening of the collar.
The small dog and cat collars are equipped with a predetermined breaking point. A harder pull triggers the breaking of the collar at this point.
If your cat is not used to collars
Rarely, mild application site reactions may occur such as scratching, redness and hair loss, which usually recover within 1 to 2 weeks without the need for collar removal. In some cases, temporary collar removal and bathing may be recommended until symptoms have disappeared. In very rare cases, application site reactions such as dermatitis, inflammation, eczema or lesions may occur. In these instances, collar removal is recommended. If signs persist or become more severe, consult a veterinarian immediately.
What is the expiration date for Seresto for cats?
