of this, Frontline Flea Control control doesn't rinse off, even with
repeated bathing. In fact, Frontline Flea Control
doesn't stop working for an entire month or more, giving your dog
or cat superior protection from fleas and ticks.
only kill fleas or ticks after they've already bitten your pet.
Frontline Flea Control doesn't wait for a flea or tick
to bite your pet; it kills fleas and ticks when they come in contact
with your dog or cat. Frontline Plus Flea Control also keeps future
fleas from biting your dog or cat by killing flea eggs and larvae
before they turn into adults.
