In addition to fipronil, which kills adult fleas, Frontline Plus contains an important addition: (S)-methoprene. Methoprene is an ingredient that kills flea eggs and larvae, which keeps ALL stages of fleas from developing and bothering your pets and your family, not just adult fleas. Methoprene mimics the juvenile growth hormone of fleas, keeping the larvae from molting and developing into more mature forms. Frontline Plus is long-lasting, fast acting flea and tick control you apply on the skin once monthly.
The fipronil in Frontline Plus spreads over the pet's body with the body oils killing 98-100% of the fleas or ticks within 24-48 hours, and controlling transmission of tick-borne disease, such as Lyme disease. It works by affecting the flea's or tick's nervous system, causing paralysis and death. Fipronil collects in the oils of the skin and hair follicles and then is released over time (up to 1 month) from the hair follicles onto the skin and hair.
