Is it necessary to treat the whole house, even where my pet does not go?
It is always a good idea to treat all the carpeting and upholstery in your home, at least one time, as a prevention. Since the flea eggs are really difficult to see, it is easily spread by your pet, without you noticing. A female flea can lay as many as 40 to 50 eggs daily on your pet. Your pet then transports these eggs and sheds them even by being in a place for a brief moment. The larvae that hatches can travel for several feet into areas your pet may never have actually been to. That is why it is important to treat your home at least once thoroughly.
