High-visibility sonic repeller with in-built solar rechargeable power pack and mow-over design. It discharges a sonic pulse into the surrounding earth every 30 seconds. This continuous disturbance within its territory repels the mole without harming it and eventually it is forced to seek a new habitat for tunnelling and feeding. For larger or irregular shaped gardens, more than one unit may be required. The built-in solar rechargeable power pack enables it to work continuously, including overnight and in poor light conditions.
