Common Yard Tunnel Diggers:
* Voles: These small, brown rodents are often called "meadow mice" and are known for their extensive tunnel networks. They create shallow, branching tunnels near the surface of the ground.
* Pocket Gophers: These larger, burrowing rodents with distinctive cheek pouches dig deep, complex tunnels that can extend up to 100 feet long. They are a common problem in gardens and lawns.
* Ground Squirrels: These active squirrels can be seen above ground but also create underground burrows for nesting and escaping predators. Their tunnels are typically less extensive than those of voles or gophers.
* Rats: While not as common in yards, rats can also dig burrows for shelter, especially in areas with available food sources.
* Moles: These insectivores aren't technically rodents, but they are notorious for their tunneling habits. Their tunnels are usually more linear and near the surface of the lawn, causing raised earth mounds.
Other potential tunnel diggers:
* Shrews: Similar to moles, shrews are small insectivores that dig shallow, short tunnels.
* Snakes: Some snake species, like garter snakes, may dig shallow burrows for shelter.
To identify the specific rodent digging in your yard, consider:
* The size and shape of the tunnels: Are they shallow and branching, deep and complex, or linear?
* The location of the tunnels: Near the surface, under trees, or in gardens?
* Any other signs of rodent activity: Droppings, gnawed plants, or tracks.
Once you know the culprit, you can take steps to prevent further damage and discourage them from digging.
