Win the war against fleas

Within 24 hours of its first bite, a female flea can begin laying eggs—as many as 50 eggs a day. So, if your pet starts out with just a few fleas, it won’t be long before your flea problem spirals out of control. That’s why it’s so important to treat every pet in your home and kill fleas before they begin to lay eggs. Trust CAPSTAR® (nitenpyram) to kill fleas fast!
