From adding a vermin-terrorizing terrier to the household to offering up a veritable vole buffet away from the garden, surely one of these suggestions will help you wrangle the rascals into submission.
This is my favorite:
“Several years ago I discovered that voles are repelled by male urine. Since then I have been setting up empty tuna tins along the perimeter of my garden and having my husband regularly urinate in them. As a result, my vole problem has completely disappeared.”
