Exhart’s MoleMover is the original electronic rodent repeller that safely and effectively helps eliminate moles, gophers, and other burrowing rodents from yards and gardens using a combination of sound and vibration signals. The MoleMover is easy to use – simply place it in the ground, then wait approximately 10 days for results. With no poisons, traps or gases, the MoleMover is safe for the environment, and around children and pets. One unit covers up to 3,600 square feet. For larger areas, use additional units. Uses 3 replaceable ‘C’ cell batteries that last up to 18 months per use (not included).
