Protecting you and your pet from fleas.

The fleas that you see on your pet are in the adult stage. What you don't see are the thousands of eggs a single adult flea can produce.

An adult female flea can lay up to 2,000 eggs in her lifetime which will be bothering your pet as adults soon. With CAPSTAR® (nitenpyram), almost all your dog's adult fleas will be gone within four hours.
