FRONTLINE PLUS is a topical once-monthly treatment that controls and prevents flea infestation and provides an effective barrier against ticks on dogs and cats.
FRONTLINE PLUS is fast-acting and is guaranteed to kill 100% of fleas on your pet and larvae in their environment. It eliminates re-infestation of new adult fleas for up to one month after treatment and prevents the development of flea larvae, pupae, and eggs for up to three months after treatment. FRONTLINE PLUS is waterfast. It is not recommended to bathe or shampoo dogs during the 48 hours after treatment. Thereafter, bathing, water immersion, or exposure to sunlight will not reduce the efficacy of FRONTLINE PLUS.
