Activyl Spot-On for Medium Dogs 22 - 44 lbs (10-20 kg) - 4 Pipettes

The solution contains the active substance Indoxacarb which works using a process called bio-activation. This mode of action uses enzymes inside the flea to activate and produce an active compound that interferes with the flea's nervous system.

Once activated, Activyl will not only kill adult fleas but also break the flea life cycle and prevent eggs developing into larvae.

Each 1.54ml pipette contains 300.30mg Indoxacarb.

It is also quick-drying, fragrance-free, water fast on dogs, and remains effective even after bathing.
