When there are piles of snow, it allows them to spread out into areas that they normally cannot access safely.
But even though we did not have a lot of snow, we did get one heavy snowfall. It was enough to pile up along our privacy fence. Lo and behold when the snow melted, the evidence was there. The little creatures had spent enough time to make some trails and tunnels in the lawn.
What can be done with vole trails? The damage done by voles is usually just on the surface. They take grass blades to fashion nests. The trails are stripped of the grass and create ugly patches in the lawn.
Generally, I recommend a small bag or two of topsoil and a few handfuls of grass seed. Most often the damage will go away and not be noticeable once the grass starts to grow. In some cases, a small portion will not recover without the help of some soil and grass seed. Just to be safe, adding some soil and grass seed will speed up the process.
