Moles
While moles can be beneficial to the soil because they cultivate and aerate the dirt while tunneling for food, homeowners object to the unsightly molehills and tunnels that can destroy a beautiful lawn. According to the National Mole Hunters Association, moles can dig 100 feet of tunnels in a single day. They dig because they are looking for food – mainly earthworms, grubs and other insects. Be aware that when moles are present, voles and shrews are likely to be around.
Voles
Voles are herbivores that travel through mole tunnels and survive by eating grasses, bulbs, tubers, and herbaceous plants. While moles damage your plants when looking for insects, voles are actually eating your vegetables and flowers! Voles burrow into the root systems of shrubs and trees and they will gnaw on tree trunks causing substantial damage.
Shrews
Shrews create dime sized holes in the lawn gaining access to existing mole tunnels. Shrews are insectivores and can be found under logs and other damp, shaded areas where insects live. Many people will leave shrews alone since they eat insects and grubs and are not as destructive as moles and voles.
How To Get Rid of Them
There are several approaches to ridding your yard of moles, voles and shrews. You may have to try more than one method depending on how many types of creatures are living in your mole tunnels. The most successful way to eradicate moles is to trap them using a mole trap that is carefully positioned into the mole’s active tunnel. Voles and shrews can be trapped and killed with mouse traps. Another option is to use poison. While many people don't like this option, it can successfully rid your yard of destructive lawn vermin.
If you don't want to kill the animals, you can try different methods that are meant to deter and discourage them from returning. Southern States offers mole repelling products for this purpose. Since moles primarily eat earthworms and other subterranean insects like grubs, removing the food source can often eliminate the problem. Apply grub control as part of your lawn maintenance program. Also, keep your grass cut regularly and remove old logs, brush, leaves and rocks to eliminate the insects that moles and shrews feed on. Removing overgrown vegetation and debris can help control voles. Getting an outdoor cat is a great idea too!
