The Ultrasonic Pest Repellent is effective for an area up to 800- 1,200 Sq. Ft.Since ultrasonic sound can’t penetrate wall, one room one unit is recommended. As for large storage area with serious pest , additional units is required. Mild Humming Sound:The waves that this repeller sends are far beyond the hearing range of human-beings. The machine produces mild humming sound for pest repelling function.
