The ‘No Bite’ way to protect against fleas

With Seresto, fleas and flea larvae are killed through contact with your pet’s skin, hair and dander, whereas some other treatments require fleas to bite your pet in order to be affected.

Seresto® safety information

Consistent low dose ensures safe, continuous protection for both cats and dogs.

Seresto for cats and small dogs includes a double safety system

  • A ratchet-release mechanism enables the collar to widen
  • A pre-determined breaking point provides a second layer of protection.  In the unlikely event of your pet becoming trapped, their own strength will trigger release.  

How Seresto® works

Seresto works with a patented controlled release mechanism.

  1. Active ingredients are integrated into Seresto’s polymer matrix.
  2. Low doses of active ingredients are released from the matrix over time and absorbed through the lipid layer of the pet’s skin and hair.
  3. The active ingredients are quickly distributed throughout the entire body surface to protect the pet for up to 8 months.
