Ultrasonic Prevention: Sends out a sound wave every 20 to 30 seconds. This device uses an intermittent vibration generator that emits vibrations and ultrasound between 400 Hz and 1000 Hz. Solar Energy Saving: Solar panels provide sufficient energy by absorbing light, eliminating the need for additional batteries and charging. It is much cheaper than battery-powered insect repellents. Waterproof and Durable: This solar insect repellent is waterproof, so you don't have to worry about it not working on rainy days. Corrosion resistant and will not contaminate the soil even after long hours of work. Effective and Safe: No annoying chemicals or pesticides, no traps, no dead animals. Will not cause any harm to your cats, dogs and other pets. Environmentally friendly: Ultrasonic mouse repellents can effectively kill hamsters, voles, snakes and other destructive rodents. The device releases vibrations into the ground, which disturb the animals and look for a more comfortable place.
