In terms of damage done to your garden, voles are the real culprit. Although moles can cause some havoc on your lawn with their tunneling and mounding, they're insectivores, feeding mostly on earthworms and bugs. Voles, on the other hand, eat plant roots, bulbs and the bark of young trees (especially fruit trees).

Is it bad to have voles?

Voles are not considered to be physically dangerous to people; but, they are dangerous in the sense that they can spread disease through their urine and feces and introduce parasites onto your property. They also can cause major damages to lawns, fruit trees, landscaping, and grain crops.

Should you kill voles?

The short answer is yes. Voles can be very damaging to a lawn and yard. They love to chew the vulnerable stems of young trees and woody ornamental plants, causing severe damage and dieback.
