\n Frontline Gold has a new ingredient, pyriproxyfen, which helps kill the next generation of flea eggs and larvae before they have a chance to develop into adult fleas. Frontline Gold starts killing fleas in just 30 minutes. Frontline Plus kills 100% of adult fleas on your pet within 12 hours and 100% of all ticks and chewing lice within 48 hours.\n
