Frontline Plus uses S-methoprene to kill both the larvae (junior) form of fleas and flea eggs. Adult fleas are killed by fipronil. These medications also kill the eggs, larvae and adult stages of the four major ticks found on dogs.
Ticks can transmit diseases to both dogs and humans. People can become infected with Lyme disease, ehrlichiosis, babesiosis, rocky mountain spotted fever, tularemia, and tick-borne relapsing fever. Advanced stages of Lyme disease can cause Lyme arthritis, a chronic joint inflammation. Neurological damage may also occur.
Directions for use: Remove applicator from child-resistant package. Hold applicator upright and snap applicator tip away from face and body. Place applicator tip through dog's hair to the skin level between the shoulder blades. Squeeze applicator, applying entire contents in a single spot to the dog's skin. Avoid superficial application to the animal's hair. Only one applicator per treatment is needed.
Frequency of application: When used monthly, Frontline Plus for Dogs completely breaks the flea life cycle and controls tick and chewing lice infestations.
