Safe Ultrasound: Generating pulsation and ultrasound, which stimulates the central nervous system of mouse and mouse, takes 3 seconds every 20 seconds, and the effective diameter of each repellant is 15M. is very effective in repelling mole and mouse and not harmful to humans, animals and poultry, ideal for garden, farm, greenhouse Smaller, more efficient: The fact that the functionality and is retained, the size of the mole scare is reduced, which takes up less space, and the overall color can be integrated into the environment. 3.5cm * 3.5cm amorphous silicon solar panels, energy conversion up to 10%. There can preferably be sufficient energy on a cloudy day. No electricity consumption, no costs, very environmentally friendly and reduce electricity costs. Environmentally friendly materials: Made of high quality ABS and aluminum pipes, IP65 waterproof and corrosion resistant, and does not pollute the ground even after long work.
