Inside the unique polymer matrix of Seresto® are two active ingredients:
Flumethrin works together with imidacloprid to provide dual action against fleas and ticks. No other treatment has this combination of ingredients [FIG. 1].
The active ingredients spread from the site of direct contact [FIG. 2] over the skin surface of the cat or dog [FIG. 3 & 4].
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 over eight months, a duration that makes it clearly different from other collars.
The active ingredients of Seresto® are contained within the Bayer Polymer Matrix, making it water-resistant. Therefore it is unnecessary to remove the collar before the pet is immersed in water. Seresto® remains effective following a shampoo treatment, swimming, or after exposure to rain or sunlight. Under normal conditions, effectiveness lasts for eight months. In order to maintain an 8-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.
