solar rodent repellent is a species of rodent repellent that uses solar panels to recharge the battery. It stimulates the nervous system and pain system of mice through ringing wave vibration cycle, so as to achieve the purpose of chasing away rats. The rat repellent deteriorates the living environment of rats, reduces the ability of activity and reproduction, and makes them degenerate to extinction naturally! The device can also drive away moles, snakes, ants and pests Features: Solar Ultrasonic Tips: Emits a 400 Hz beep sound when vibrating every 30 seconds. The animal feels the noise and vibrations very irritating Take refuge from a certain area. Solar energy: Powered by a rechargeable solar battery, with charge rates of just 6-8 hours, for 5-7 days of use and up to 7000 square feet of coverage. Human waste and not: be safe for animals and humans, without getting rid of the body, it is safe for the soil environment and nearby planting. Waterproof and durable: waterproof and corrosion resistant and flame retardant ABS material also apply to rainy days. Insert into the ground, and make sure the top is about 2 inches above the ground to avoid water flowing inside. Features: solar panel power supply: 2V / 45mA solar panel size: 70 90MM Battery: 1 1.2V / 600mAH "AA" Ni-Cd nickel cadmium battery Material: ABS Frequency: 400-1000HZ Item Size: 25 * 6.2 * 6.2cm Weight: 120 g principle: 1.Use solar energy for charging and discharging. 2.According to scientific research, animals are very sensitive to vibrations, and even small vibrations can be felt, so this product is based on the principle of transmitting vibration waves, making it unbearable and fleeing the scene. Range of use: This product is suitable for open areas like open meadows and parks. The effective range is within 100 square meters. The higher the effect, the better. It is recommended to use 2-3 products if the garden is relatively large. Precautions: 1.Charging method: solar charging, plug directly into the place where there is sunlight to the load. The effect will be better. 2.The product is rainproof, but not rainproof. Please do not exceed the safety line during installation. If the rain height exceeds the hafety s line, please take this product away until the rain water recedes. 3.Installation method: the switch is turned on, and it works automatically! This product will make noise and vibration every minute. Packing list: 1 * Solar Mole Repellent< /ul>
