Seresto Flea & Tick Collar
The Seresto® collar uses a unique polymer matrix containing two active ingredients that spread across the skin surface of your dog:
- Imidacloprid – used for years to control flea infestations
- Flumethrin – effectively kills and repels ticks
- The combination of imidacloprid and flumethrin provides dual action against fleas and ticks; no other product uses this pairing
Sustained Release Technology:
Seresto® works similarly to a monthly topical treatment in that the active ingredients spread from the site of direct contact across the skin surface. The collar continuously releases active ingredients, which are distributed through your pet’s skin and coat from head to tail. As the ingredients naturally wear off, they are steadily replenished for up to 8 months.
The long‑lasting, 8‑month duration of Seresto® sets it apart from traditional flea and tick collars.
