Frontline Tri-Act
$145.00 TTD

FRONTLINE Tri-Act® offers pet owners a safe, convenient, affordable and highly effective option that not only kills fleas, ticks, biting flies and mosquitoes fast but also repels mosquitoes, ticks, biting flies and other flying insects for a full month with a single spot-on application.

In addition to repelling flying insects, including mosquitoes and stable flies, FRONTLINE Tri-Act® is fast and effective, also killing all fleas and infesting ticks in 6 hours. This spot-on is also water-fast and does not wash off, making it a great choice for active outdoor dogs.

FRONTLINE Tri-Act® is a spot-on treatment exclusively for dogs from 8 weeks of age and 2kg body weight.
