Answer: Voles tend to be very destructive to plantings because they devour plant roots. Unfortunately, moles and voles are difficult to control. In my experience, the most effective control is achieved by trapping them. You might wish to consult with your county extension as to specifically deciding the most effective methods of control, such as how best to go about baiting and setting the traps and protecting any pets or other animals in the area.
