Solar rodent repeller is a kind of rodent repeller that uses solar panels to charge the battery. It stimulates the nervous system and pain system of mice through the buzzer cycle vibration wave, so as to achieve the purpose of driving away rats. The rat repellent deteriorates the living environment of rats, reduces the activity and reproduction ability, and makes them degenerate to extinction naturally! The device can also drive away moles, snakes, ants, and harmful organisms Features: Solar Ultrasonic Spikes:Emit a beep sonic of 400Hz when vibrating every 30 seconds. The animal feels the sound and vibration highly irritating so flee from a certain area. Solar Powered:Powered by a rechargeable solar cell, with charging rates of just 6-8 hours, for 5-7 days of use and up to 7000 sq ft of coverage. Human and No mess:Be safe to use around pets and humans, no dispose of the body, it's safe for soil environment and nearby planting. Waterproof and Durable:Waterproof and corrosion-resistant and ABS flame retardant material also apply to rainy days. Insert it into the soil, and make sure the top part is about 2 inches above the ground to avoid water flowing into the interior. Specifications: Solar panel power: 2V/45MA Solar panel size: 7090MM Rechargeable battery: NI-CD nickel-cadmium battery 11.2V/600mAH "AA" Ni-Cd Material: ABS Frequency: 400-1000HZ Item size: 25*6.2*6.2CM Weight:120g principle: 1.Use solar energy to charge and discharge. 2.According to scientific research, animals are very sensitive to vibration, 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 such as open grasslands and parks. The effective range is within 100 square meters. The closer the effect, the better. It is recommended to use 2-3 products if the garden is relatively large. Precautions: 1.Charging method: Solar charging, directly plug in the place where there is sunlight to charge.
