We kill more than just adult fleas.

Killing adult fleas
just isn’t enough.

Since adult fleas represent approximately 5% of the total flea population,1 they’re only part of the problem.

To stop infestations, it’s also important to affect other stages of the flea life cycle3—killing flea eggs and larvae. By breaking the cycle, it helps prevent fleas from reproducing.
