Vole Tunnels or Burrows
Tunnels or burrows in lawn areas are caused by small, mouse-like animals called voles. Voles are most active in lawns that are near unmown pastures or wooded areas, or where dense vegetation provides shelter for them. Voles feed on grass and dig tunnels to move about under the lawn.
Populations of voles are cyclical, so they may appear for a couple of years and then disappear for a number of years. If they are causing extensive damage to trees, shrubs and lawns, use baited mousetraps to reduce their population.
