There are 4 main ways to treat a flea infestation:
• Kill newly arriving adult fleas on your pet. It may take months to kill all the fleas emerging from pupae in your home.
• Stop further infestation of your home by inhibiting the hatching of viable flea eggs and preventing the development of larvae into adult fleas.
• Clear your home and the environment of flea eggs, larvae, and pupae that are already there.

Points 1, 2, and 3 can all be achieved by treating your pet regularly with a product, such as FRONTLINE® Plus, that contains two active ingredients (one to kill adult fleas, the other to prevent the development of eggs and larvae).

Flea pupae are protected by their cocoons—all pupae will have to hatch out and be killed as adult fleas on the pet. It can take several weeks for all pupae to hatch from an infested environment.
