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.

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 backyard 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 backyard 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.

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.

We recommend bathing BEFORE applying product. 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. 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 5 months for flea control and reduced to 7 months for tick control. There is no need to remove the collar for bathing. Please use a non-stripping, pet shampoo.
