Chipmunks are a familiar sight in most gardens, but unlike other harmless visitors, they can do extensive damage to a yard by digging burrows and tunnels in the soil. These tunnels not only look unsightly, they can weaken the ground and injure human visitors in your garden. Filling in chipmunk holes can save your lawn or garden from soil collapse, and spare you and your guests a few nasty falls.
Use a trowel or shovel to scoop up some extra soil from your yard and pour it into a bucket. Pick up extra soil from a home service centre if you do not have enough spare soil available.
Pick up a few bags of coarse gravel for a home service centre. Purchase more gravel than you may consider necessary, since it is difficult to gauge the depth of the chipmunk holes from the surface.
Pour gravel down the chipmunk holes to fill them in, leaving a 2 to 3 inch space leading to the lawn's surface. Chipmunks cannot easily dig through gravel, and will most likely not attempt to re-dig the hole.
Use your trowel or shovel to fill in the remaining space and the area leading up to the lawn with soil. Allow the fresh soil to pile at least 1 inch above the surface to create a mound.
Use your shovel to tamp down the soil. This will compact it, make it less noticeable and less hazardous for human travellers to walk on.

- Refrain from using potting soil to fill the chipmunk holes. Potting soil may not be dense enough to properly fill in the holes.
- Always wear safety gloves when using hand tools to avoid injury.
