I do get some voles in my yard and I use the rat bait to kill them. I put the bait into a coffee can with a secure lid, cut a small hole in the lid and then lay it out for those nasty voles to feast upon. It is safe to use this method around animals since the lids are secure.

Once you have effectively removed the voles from your garden it is important to practice integrated pest management to prevent your garden from repeated infestation of voles.

A vole pest problem is most likely to arise in yards where voles have abundant amounts of vegetation and debris to hide under and build their nests. If you keep your garden weeded, avoid planting dense ground covers such as creeping junipers, and keep your lawn mowed, you’re less likely to have to worry about voles in the first place. You have to be particularly careful about applying mulch too close to trees and shrubs. During winter keep snow cleared away from shrubs and young trees. You can also protect young trees by wrapping the lower trunk with wire mesh.
