Habitat Modification
Deter & Reduce Vole Populations with IPM (Integrated Pest Management)
You can deter vole populations and reinfestation, especially
voles that forage above ground,
by making their habitat less suitable for them. Lawn and turf areas
should be mowed regularly. Close mowing in the fall before snow arrives
can reduce damage to the lawns. Remove weeds, heavy mulch, and dense
vegetative cover surrounding the lawn areas. These things provide food
and protection from predators and the environment. If you remove this
protection, their numbers will decline.

You can reduce the chances and areas from which voles can invade your landscape and garden by regularly mowing, spraying with herbicides, removing overgrowth of heavy vegetation, and cleaning up ditch banks, and catching the birdseed that falls from your bird feeder. It is especially important to do this before winter snow arrives.
Fallen birdseed from feeders attracts voles to an area. Cleanup and prevention of birdseed falling to the ground will reduce vole infestations.
Landscape fabric or plastic mulch that is placed around your shrubbery provides an inviting place for burrowing vole types. If removed then it may expose them to more predators.

To exclude voles from entering your vegetable garden, you can surround the perimeter of the garden with 24" wide metal flashing or ¼ inch wire mesh. Bury it 12 to 14" in the ground and leave the other part exposed. This will keep voles from surrounding areas from entering the garden. Voles within your vegetable garden should be eliminated with traps instead of the Vole Control Bait Station System because the bait is not registered for vegetable gardens.

If you have vole problems in your vegetable garden, then don't
leave leftover crops over winter.
Remove the potatoes and carrots and any other root crops that may
provide a food source for winter. Also remove any refuse for them
to hide in.
If you have fruit trees be sure to pick up all the fallen fruit so the voles can not feed on it.
If vole populations are high and severe economic damage is occurring, it will be necessary to include both the Vole Control Bait Station System as well as implementing habitat modification to control vole populations.
