The GBruno Solar Mole Repeller uses advanced buzzer vibration technology to emit sound waves between 400 and 1000 hertz, effectively deterring moles, gophers, voles, and other burrowing rodents from your outdoor spaces. Each stake covers up to 323 square feet and emits three-second sonic pulses every 30 seconds that penetrate the soil, encouraging pests to leave the area without the use of harmful chemicals or traps. The repeller is powered by a monocrystalline solar panel that charges a rechargeable nickel-metal hydride battery, eliminating the need for battery replacements and ensuring continuous operation in sunlight. Constructed from durable ABS plastic, each waterproof stake measures approximately 10 inches tall and can be easily inserted into the ground in gardens, farms, yards, patios, or near ponds. This humane solution is safe for humans and pets, providing an eco-friendly way to protect your property from destructive rodents. This product contains chemicals known to the State of California to cause cancer and birth defects or other reproductive harm.
