Hello Ed,

What is happening with your lawn that leads you to conclude you have voles? Vole damage to lawns appears after snow-pack melts. It is then that you discover the feeding on grass plants that occurred under the snow. In southeastern Michigan and Livingston county, there was not sufficient snow cover this winter to really protect voles as they fed.

Are you having lawn damage right now? Then it is not likely voles. It could be moles instead.

Here is an article on voles and examples of their damage:
