Frontline has greater efficacy against which type of parasite?

Frontline is primarily designed as a topical treatment for external parasites, specifically focusing on fleas and ticks. Its active ingredients, such as fipronil and (in some formulations) (S)-methoprene, are known for their effectiveness in disrupting the nervous system of these parasites, leading to their elimination.

When considering its efficacy, Frontline has shown particularly strong effectiveness against ticks. This is significant because ticks are not only a nuisance but can also transmit serious diseases to pets and humans, such as Lyme disease. The formulation of Frontline allows it to target adult ticks more efficiently, providing pet owners with a reliable means of protection against these external parasites.

Fleas are also affected by Frontline, but the question specifically asks about which type of parasite Frontline has greater efficacy against. Ticks tend to have more resilience and require specific targeting, making Frontline's action against them particularly notable when compared to its action on other types of parasites like roundworms and tapeworms, which are internal parasites and require different deworming medications. Therefore, the answer regarding Frontline’s greater efficacy clearly emphasizes its role in combating ticks in particular.
