FRONTLINE PLUS contains two active ingredients to break the flea life cycle at every stage. One ingredient, fipronil, kills the adult fleas on your pet while the other ingredient, (S)-methoprene, kills flea eggs and prevents larval and pupal development. (S)-methoprene prevents fertile flea eggs being laid throughout the month, preventing reinfestation of your pet and contamination of your home environment. Fleas can breed all year round so ensure you continue to treat your pet in winter to achieve the best flea control.

 

Kills Fleas, Ticks, Flea Eggs and Larvae. Frontline Plus For Cats provides fast, effective and convenient treatment and control of fleas and ticks. Frontline Plus for Cats remains effective even after bathing, water immersion, or exposure to sunlight.
