Activyl® is the first flea product that works through bioactivation.
Most cats and dogs will pick up fleas often in their lifetimes. It's just one of those things. But it is unpleasant. If you were a dog or cat, you'd want a treatment that was effective at killing fleas, yet gentle*. That's why we've developed Activyl®, a spot-on flea treatment that works through bioactivation. This means it only switches on inside the flea, to deliver full flea-killing power.
* When used according to label recommendations.
Did you know?
Activyl® is an innovation in monthly spot-on flea treatment and prevention that works differently from conventional flea treatment as it only becomes fully active on contact with flea enzymes.
It's also quick-drying, fragrance-free, water fast on dogs, and remains effective even after bathing.
