*Data on file.
†Seresto® is water-resistant and remains effective following a shampoo treatment, swimming or after exposure to rain. 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.
