The open area behind our back fence is home to hundreds of voles. The hills look like this:
During the summer, I can successfully restrict their intrusion into my yard by putting poison into the holes.
But, nearly every winter we get significant snowfall that ends up sticking around for months. By the time it melts, much of the lawn has been torn up with vole runways, which do grow back eventually but often leave the lawn significantly lumpier.
Is there any way I can prevent the voles from running around under the snow cover undetected, eating my lawn?
