Although mice are easily frightened by strange or unfamiliar noises, they quickly become accustomed to regularly repeated sounds. Ultrasonic sounds, those above the range of human hearing, have very limited use in rodent control because they are directional and do not penetrate behind objects. They also lose their intensity quickly with distance. There is little evidence that electronic, sound, magnetic, or vibrational devices of any kind will drive established mice or rats from buildings or provide adequate control. Although cats, dogs, and other predators may kill mice, they do not provide effective mouse control in most circumstances.
Mice often live in very close association with dogs and cats.
Mouse problems around homes often are related to the food, water and shelter provided for the pet. If rat control is also a problem, see NebGuide G92-1106, Controlling Rats .
