My field/yard, which I keep mowed, have been invaded by voles. Since my property is so large, over 7 acres, I have very little fine grasses, mostly field grasses. Every step is a sinkhole. Should I be killing the grubs in the soil to get them to move on?

Thank you for your question. We need to clarify if you have voles or moles or both? In the wild, voles forage on native vegetation and provide a valuable food source for predators such as weasels, hawks, and snakes. In home landscapes, voles can cause damage by eating flower bulbs, girdling the stems of woody plants, and gnawing roots. Damaged plants can be more susceptible to diseases or water stress during periods of drought. The following fact sheets will give you information about voles. http://www.ces.ncsu.edu/nreos/wild/wildlife/wdc/voles2.html http://www.extension.org/pages/8677/vole-damage-management#.Uw0Pn_3wvwI http://extension.missouri.edu/p/G9445 (good illustrations)
Moles are mammals that feed mostly on insects, earthworms and some seeds. Refer to the following fact sheet for specific information on the habits of moles and their control: http://icwdm.org/handbook/mammals/mam_d51.pdf http://bygl.osu.edu/content/tunneling-moles
