What are the differences between frontline and advantage flea treatments?
Here you go: Advantage: The active ingredient is imidacloprid, which acts on the nervous system of the flea to cause paralysis and subsequent death. Advantage stops biting fleas in three to five minutes and starts to kill adult fleas within an hour after application.1 Within 12 hours of application, 98-100 percent of fleas are dead. Frontline: All FRONTLINE products offer control of fleas, killing up to 100% of adult fleas on your pet within 18 hours. And with an added ingredient to kill flea eggs and larvae, FRONTLINE Plus completely breaks the life cycle of these dangerous and annoying pests. So that’s the main difference. Advantage kills live fleas, Frontline claims to also kill the eggs, allegedly preventing future outbreaks. And it can also be used for ticks. (active ingredients: fipronil and (S) -methoprene) So there you go.
