What is Seresto?

Seresto is an effective, reliable alternative to monthly flea and tick topicals. This dual-action collar for dogs and cats repels and kills fleas & ticks for 8 consecutive months. If a flea or tick is repelled, it cannot attach and transmit disease-causing organisms, Seresto uses innovative technology to release the active ingredients in controlled doses over an extended period of time, this means effective long-term flea and tick control without the inconvenience of monthly applications. Seresto protects your pet from fleas, flea eggs, flea larvae, ticks, as well as sarcoptic mange on dogs without odor or mess. It is available in three formulations for small dogs, large dogs, and cats.

If shampooing the dog, it is recommended to use a soap free shampoo.
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.

The collar should be worn continuously for the full protection periodThe Seresto collars have two safety features in case of needing emergency release: a ratchet release mechanism and a manufactured breaking point, which will give way if your pet is trapped or snagged by their collar
The Seresto collar can be worn alongside your pet's normal collar.
Frequent shampooing or exposure to water (e.g. swimming) while wearing the collar may reduce efficacy.
