Frontline Plus and Frontline are both flea and tick treatments produced by the same manufacturer, but they have some differences in their formulations and effectiveness.
Here's a comparison:
-
Active Ingredients:
- Frontline Plus: Contains fipronil and (S)-methoprene. Fipronil kills adult fleas and ticks on contact, while (S)-methoprene prevents flea eggs and larvae from developing.
- Frontline: Contains fipronil only. It kills adult fleas and ticks but does not contain an insect growth regulator like (S)-methoprene.
-
Coverage:
- Frontline Plus: Provides broader coverage by targeting adult fleas, flea eggs, flea larvae, ticks, and chewing lice.
- Frontline: Primarily targets adult fleas and ticks.
-
Effectiveness:
- Frontline Plus: Due to its additional active ingredient (S)-methoprene, it may offer more comprehensive protection against fleas by preventing the development of eggs and larvae.
- Frontline: Effectively kills adult fleas and ticks but may not provide the same level of prevention against flea eggs and larvae.
-
Duration of Action:
- Both Frontline Plus and Frontline typically provide protection against fleas for up to one month and against ticks for up to three months, depending on the type of tick.
In summary, Frontline Plus is generally considered more effective and provides broader coverage compared to Frontline because of its additional active ingredient, (S)-methoprene, which helps prevent flea infestations by targeting flea eggs and larvae. However, the choice between Frontline Plus and Frontline may depend on factors such as your pet's specific needs, the severity of the flea problem, and your veterinarian's recommendations. It's always a good idea to consult with your veterinarian to determine the most suitable flea and tick control option for your pet.
