What kind of grass do you have? If you've got KBG, it will repair itself once it starts actively growing.

I have KBG but I don't think these are new tunnels, I think they may have been there awhile and never filled in. The soil is sunken where the tunneling was so there's been no soil for it to fill into. You do have a point though. I think if I add compost to level the ground back out, there will be soil there for the KBG to grow into. Thanks. You helped me answer my own question.

I have KBG. When I get a vole tunnel in the lawn, I walk along the tunnel gently. At the dirt mound area, I try to push back some of the dirt with my foot and make it level and the excess dirt I kick or rake to surrounding lawn to keep it from being a mound. Usually the grass all fills in in a few weeks. I only wish the voles would stay away from the landscaping edging near the house! Rachel

Voles or moles? I thought vole damage was at the surface and was just paths that appeared when the snow melted. What you're describing sounds more like moles.

I have whatever they had in Caddyshack - but they are not THAT active (thank goodness!) Seems to go in spurts, some years worse than others. Tried a castor oil spray near the landscaped areas , but that did not seem tomake a difference. Learned to live with their occasional tunnels.

"This is a hybrid. This is a cross, ah, of Bluegrass, Kentucky Bluegrass, Featherbed Bent, and Northern California Sensemilia. The amazing stuff about this is, that you can play 36 holes on it in the afternoon, take it home and just get stoned to the bejeezus-belt that night on this stuff."
