Moles and voles can wreak havoc on your lawn. From tunnels and burrows to channels and holes, one little rodent can create lasting damage. Fortunately, these degradators of the dirt aren’t necessarily a death sentence for your lawn. With the right information, and a little proactivity, you can get back to growing a thriving lawn this summer.
It is rare to spot a mole above ground. These solitary rodents spend most of their lives underground. With broad feet fit for digging, and a coat of shiny dark fur, these insectivores feed on earthworms, grubs and other inverts but love to use grass for nesting. They create grass-lined burrows 1 ½ to 2 feet below the surface, often under tree roots, sidewalks, and buildings.
Unlike moles, voles live above ground. Easily mistaken for mice, voles are most commonly spotted darting across lawns or through fields. With their compact bodies, brown fur and short hairy tails, these herbivores feed almost exclusively on plants and turf. Well suited for digging, voles are active year-round, both day and night, but typically are more prevalent in areas with higher snowfalls.
Tunnels, channels and even holes in your lawn are a great indicator of rodent problems. But how do you know if it’s a mole, or some voles to blame?
No Entry Hole Then It’s A Mole
Look for low ridges of soil or mounds of dirt. If there are no entry holes, then you are probably dealing with a mole.
Burrow In The Snow Then It’s A Vole
If there is a ground burrow or entry hole (usually about 1 inch across), then you have voles. Check for runways in the turf to be sure. They will be most visible after snow melts.
One of the easiest ways to mitigate moles and voles is to simply collapse their tunnels and channels. You should level out raised mounds or tunnels by hand (or foot) or with a heavy lawn roller. Not only is this approach safer, but it makes mowing and maintenance easier. Once you’ve eliminated and filled in their tunnels, burrows and nests, it’s important to take steps to prevent them from resettling the area.
Deter Pests with Pets
The most natural way to deter moles is with predators. Dogs or cats will naturally chase, hunt and antagonize moles and voles, ensuring your lawn never becomes hospitable.
Repel Rodents with Castor Oil
Using castor oil-based mole and vole repellents is another effective and non-toxic solution. With every form of repellent, it is important to follow the labeled instructions. Improper application can result in moles and voles just moving to another area in your yard. For best results, coordinate with neighbors to eradicate rodents from the entire area.
Set A Trap
If pests persist, traps are another non-toxic solution. When using a trap, be sure to check them often because trapped rodents will attract scavengers. Whether you prefer a live or traditional trap, removing the captured rodents is key.
Call the Professionals
The secret to successful DIY pest management is knowing when to phone a friend. Especially when it comes to mammalian pests. If moles and voles endure these options, call a local professional or consultant.
Sunday Pro Tip: Voles often feed on fallen or discarded bird seed. Eliminate this food source by placing bird feeders above pavement, pavers or cement. Then, sweep up and either compost or dispose of the seed.
At Sunday, we recommend using an Integrated Pest Management (IPM) approach to pest control, not poisons and baits. In the wild, poisoned rodents don’t just disappear, they are often fed on by other predators and scavengers, especially birds of prey like raptors and owls. This moves bait or poison through the food chain and into the natural ecosystem where it causes inadvertent death and illness in those animals. These poisons also create an unnecessary risk for kids and pets. For safety sake, it’s always best to pass on poison.
