What is what animal is digging holes in my yard?

It's tough to say exactly what's digging without more clues like the size/shape of the holes, location in your yard, and any droppings or tracks nearby. However, here are some common culprits, along with information that might help you narrow it down:

• Squirrels: Often dig small, shallow holes to bury nuts and seeds. These are usually only a few inches across.

• Chipmunks: Similar to squirrels, but their holes may be entrance points to underground burrows. They also create shallow holes for food storage.

• Moles: Create raised tunnels and molehills (piles of dirt) as they tunnel underground in search of insects and worms. Their holes are usually a direct entry point to their tunnels and not always visible.

• Voles: Also create tunnels, but their tunnels are usually at the surface, creating visible runs through the grass. Their holes are typically small and hidden under vegetation.

• Raccoons: Can dig larger holes, often in search of grubs or insects. They might also dig up turf to get at earthworms. Their digging is usually more destructive than squirrels or chipmunks.

• Skunks: Similar to raccoons, skunks dig for grubs and insects, leaving cone-shaped holes.

• Groundhogs (Woodchucks): Dig large burrows with multiple entrances. These burrows can be quite extensive and damaging.

• Dogs: If you have a dog or neighborhood dogs visit, they might be digging for fun, to bury things, or to try to catch rodents.
