What is the Difference Between Frontline and Frontline Plus?

Frontline and Frontline Plus are both flea and tick prevention products for pets, but they have some differences in their formulations and effectiveness. The main differences between Frontline and Frontline Plus are:

1. Active Ingredients: Frontline Original contains Fipronil as its active ingredient, which is effective against adult fleas, flea allergy dermatitis, ticks, and biting lice. Frontline Plus, on the other hand, contains an additional ingredient called Methoprene, which kills all stages of the flea lifecycle, including flea eggs, larvae, and adult fleas.
2. Flea Protection: Frontline Original protects your pet against adult fleas only, while Frontline Plus provides protection against all stages of the flea lifecycle, including flea eggs, larvae, and adult fleas.
3. Tick Protection: Both products are effective against ticks, but Frontline Original is specifically mentioned to protect against paralysis ticks and brown dog ticks.
4. Methoprene: Frontline Plus contains Methoprene, an ingredient that sterilizes female fleas, preventing them from laying eggs and therefore breaking the flea lifecycle.

In summary, Frontline Plus offers more comprehensive protection against fleas and ticks due to its additional active ingredient, Methoprene. Both products are effective in protecting pets from fleas, ticks, and lice, but Frontline Plus provides a broader range of protection by targeting all stages of the flea lifecycle.
