Solar Powered Mole Repellent to Secure your Garden Environment Read instructions emailed to you thoroughly. The repeller transmits its signal in all directions approx. 50 ft so they can be placed approx. 100 ft apart in high risk areas, it is always recommended to use two or more units to get the best results. Insert the spike into the ground paying attention not to damage the unit. The spike should be firmly planted while leaving the base of the head 1-2" above the ground. We suggest use a crowbar to first make a small hole and gently push the spike in or dig a small hole and backfill with earth after the unit is in place. If the repeller unit is placed on a slight angle facing the sun often a better battery life can be achieved through better charge rate. Normally the only maintenance required is with a soft cloth, wipe the solar panel cover to remove any excess dirt and grime. When the units are first installed we suggest you watch any children or pets in case they come across any resident snakes that are driven out.
