Ultrasonic pest control devices have been on the market for a long time. Their manufacturers and sales personnel lead you to believe that the high-pitched sound produced by the little black boxes (some with red lights to show you they are working) can only be heard by pests, not by other animals or humans. The sounds are so annoying, they say, that pests either leave or die. They also claim that the devices won't harm your pets, like gerbils and hamsters.
