These voracious little pests can decimate a bed of lilies in short order, eating the tasty bulb and leaving the stalk to wither and mysteriously die. Tulips are another favorite food of these gluttonous rodents, so if you have difficulty growing tulips you must consider the possibility that voles are living, rent-free, on your property. You should take precautions before making an investment in bulbs. There are several ways to discourage vole damage or eliminate them from your garden. Getting rid of moles will help.
Voles use mole tunnels to navigate underground and save themselves some digging.
Moles will only stick around if there is a source of food they like, usually beetle grubs. If you see a lot of pale, pasty grubs when you dig in your garden and see mole runs in the lawn you can take steps to kill the grubs. Applications of Milky Spore disease is a good way to rid lawns of beetle grubs. As grubs eat grass roots, they turn into Japanese beetles, ridding your soil of them. This will encourage the moles to seek happier hunting grounds, taking the free-loading voles with them.
