Frontline Plus is a topical flea and tick treatment for dogs and cats that works by targeting both adult fleas and ticks, as well as interrupting the flea life cycle. It contains two active ingredients: fipronil and (S)-methoprene.
-
Fipronil: Fipronil is a broad-spectrum insecticide that works by disrupting the normal function of the nervous system in insects. When Frontline Plus is applied to your pet's skin, fipronil is absorbed into the hair follicles and oil glands. As fleas and ticks come into contact with your pet's fur, fipronil is transferred to them, causing hyperexcitation and death.
-
(S)-Methoprene: (S)-methoprene is an insect growth regulator (IGR) that prevents flea eggs and larvae from developing into adult fleas. It mimics the juvenile growth hormone of fleas, disrupting their growth and development. (S)-methoprene also affects flea eggs, preventing them from hatching and developing into larvae.
Together, these two active ingredients in Frontline Plus provide a comprehensive approach to flea and tick control:
- Fipronil kills adult fleas and ticks on contact, preventing infestations and reducing the risk of disease transmission.
- (S)-methoprene interrupts the flea life cycle by preventing flea eggs and larvae from developing into biting adults, helping to control the population of fleas in your pet's environment.
Frontline Plus is applied directly to the skin between your pet's shoulder blades, where they cannot reach and lick it off. It then spreads across the skin and hair follicles, providing long-lasting protection against fleas and ticks. Frontline Plus remains effective even after bathing or swimming, as it is stored in the oil glands of the skin and is gradually released over time.
Regular application of Frontline Plus according to the manufacturer's instructions helps to keep your pet protected from fleas, ticks, and flea-related diseases, as well as preventing flea infestations in your home.
