Activyl Spot-On for cats and dogs

Activyl® is a monthly spot-on flea treatment that works through bioactivation. This means it only switches on inside the flea, to deliver full flea-killing power.

Unlike some flea treatments, Activyl® kills more than just adult fleas, it controls immature stages in the environment to break the flea lifecycle and prevent reinfestation. It starts working within 8 hours and keeps working throughout the month.

Activyl® has been tested on dogs to make sure it is not easily rinsed or washed off and remains effective after shampooing and swimming. Suitable in dogs > 1.5 kg from 8 weeks of age and cats from 8 weeks of age. For more information visit
