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 on/off button allows you to prolong your battery life.Safe and hygienic humane rodent removalIn many areas, mouse and rat infestations are a frustrating fact of life, forcing many families to turn to poisons or traps and to dispose of unsanitary remains.
