A. Solar powered mole repellent. It is powered by a solar panel. There is no need to replace the battery, and it is an energy-saving and environmentally friendly solar pest repeller. When using it for the first time, it needs to be charged in the sun for two days to effectively repel rodents, moles, gophers, groundhogs, chipmunks, voles, and snakes from your lawn and garden. B. How It Works: The solar mole repellent emits sonic pulses every 20 seconds through the soil, disturbing and stimulating moles to leave the area covered by the sound waves. C. Kids and Pets Safety: The groundhog repellent stake repels moles in a scientific way. It doesn't pollute your garden and is safe for humans, pets, and plants. D. Wide Coverage: Each mole repellent stake can cover up to 7,000 sq. ft in areas where rodents are often active, and a mole stake should be installed every 70 ft. E. Waterproof Design: The gopher repellent solar panel is protected with an ABS plastic case. It can be used normally even on rainy days. To avoid hindering the charging of the solar cells, the panel needs to be kept clean.
