A good aid for stealth expulsion - the nervous system of the rat is stimulated by the circulating vibration waves of the buzzer, which drive the rat away. The product also repels moles, snakes and rodents. The product does not emits no radiation when in operation and uses ultrasonic waves to remove moles etc. Solar charging - the product absorbs sunlight during the day, converts it into electric energy and stores it in the battery, turns on the switch at night, and automatically emits ultrasonic waves without manual operation or external power supply, which is more worry-free, convenient and energy-saving. DURABLE AND LONG LIFE - Made of high quality ABS material, the exterior is waterproof and durable, which not only increases the service life of the product, but also provides more stability when attached. Even long working hours do not overload the soil, and green shells easily hide in plants. Safe, reliable and environmentally friendly - the product design is more user-friendly,
