【How it Works】Rodent repellent protects your garden and lawn from moles, voles, mice, rats and other burrowing animals. 【Non-toxic and safe for children and pets】The device will not harm humans or animals. It does not use harmful chemicals, traps or poisons to kill/get rid of animals. It uses vibrations and sound pulses to penetrate the ground, leaving an unbearable environment for underground burrowing rodents and forcing them to leave the property and find other places to live. 【Waterproof and Solar Power】Waterproof adopts sturdy structure and sealed design, which enables it to work under water, wind, sun and rust. Snake vole repellers are made of high quality materials to ensure maximum durability and longevity. The mouse repellent is charged by polycrystalline silicon solar panels to accumulate power for operation during dark hours. 【Easy to install】Open the driver. Insert the nails into the ground (if the ground is hard, you may need to dig a hole), making sure the top is level
