Here’s how to plug up chipmunk burrows:
Step 1
Eliminate the chipmunk population (see above). Otherwise, filling burrows is an exercise in futility — they’ll just make new ones.
Step 2
Find tunnel entrances. Look for holes two to three inches in diameter around walls, foundations, woodpiles and stumps.
Step 3
Grab a spade and fill the holes with dirt, a mixture of dirt and fine gravel, or used cat litter, packing down as you go. Traces of cat feces and urine can signal a predator may be nearby.
Pro tip: Sand capped with quick-dry cement can be effective along foundations and walls. After stuffing the holes, cover with two or three inches of topsoil so the ground cover can grow back.
If these efforts fail, it may be time to call in a professional exterminator.
How To Deter Chipmunks
Simple actions to reduce chipmunk activity indoors and out:
- Use caulk to seal entry points around the home.
- Remove dead tree stumps, rock piles and brush near the house, garage or other buildings.
- Plant seeds and bulbs beneath a wire or plastic screen.
- Install L-shaped footers (mesh barriers) to block burrowing under foundations, sidewalks and porches.
- Place bird feeders at least 15 feet away from your home.
