A device for repelling rodents which burrow in the ground, such as moles and voles, involves a housing, an outer tube including a lower tubular portion for insertion in the ground, and an inner tube located inside the outer tube. The inner tube vibrates against the interior of the outer tube to produce audible vibrations. The device produces audible vibrations which impart sound waves and or physical vibrations to the ground in the vicinity of the device to repel rodents.
