Victor® Professional Mouse Trap

For voles, place the trap perpendicular (across) the trail in the grass, you may need to trim the grass in the spot where the trap sits. The voles will run across the expanded yellow plastic triggering plate and be captured.  Another option for voles is to place a trap at each hole and cover the hole and trap with a rectangular plastic container.  When the vole comes out of the hole, they have nowhere to go outside but into the trap.
