Ultrasonic devices emit high-frequency sound waves that keep pests away, but are silent to humans. Ultrasonic frequencies are used to confuse, disorient and intimidate birds and pests within range. Pests are not harmed by these sounds, but they don’t like them and soon learn to avoid the area.
Ultrasound is most effective where sound waves can bounce off walls or ceilings, due to their direct project and short wavelength. Outdoors, expect best results in small areas.
