Koolatron Portable Ultrasonic Rodent Repeller - White

The Pest Control Portable Ultrasonic Rodent Repeller uses proven ultrasonic technology to effectively prevent rats, mice, squirrels, and more from setting up a shop in your home or cottage. Powered by 3 AA batteries, this convenient unit regularly emits one-second siren bursts at frequencies that are inaudible to most humans or pets but cause harmless discomfort to unwanted visitors. The Rodent Repeller uses dual frequencies to increase its effectiveness by preventing rodents from becoming used to one repeated sound, and with no plug required you can easily place it wherever you need it most. The LED indicator shows you when the unit is powered on and an audible test button lets you confirm that the ultrasonic function is working properly, while the onoff button allows you to prolong your battery life.
