Ultrasonic Mole Repeller - Generates pulses and ultrasound that stimulate the central nervous system of mice and mole. The vibrations emitted occur every 20 seconds with changing frequencies between 400 Hz and 1000 Hz. It is very efficient to repel mole and mouse and is not harmful to humans, pets and poultry, ideal for garden, farm, greenhouse. Environmentally Friendly and Durable - Powered by solar energy, no need for extra batteries. The improved polysilicon solar module has higher photoelectric conversion efficiency and stability, and the photoelectric conversion efficiency will not decrease after long-term use. Large Efficient Work Area - The device operates in a square pattern, approximately 15m in radius, and covers up to 650 square meters. For best results, we recommend installing 2 fixtures every 100 feet for floor surfaces used by moles. IP65 Waterproof and Corrosion Resistant - Unique gasket and design allow you to mount the device anywhere. Does not clutter the ground even
