Remove food sources: secure trash in sealed bins, clean up spilled birdseed, store pet food indoors
Eliminate attractants: remove fallen nuts, berries, and insects; trim nearby vegetation that provides cover
Block entry points: seal gaps and holes around foundations, vents, siding, and utility lines with hardware cloth or metal flashing
Use fencing: install 1/4-inch hardware cloth fencing around gardens/plant beds, extending at least 12–18 inches below ground and 2–3 feet above ground
Make yards less hospitable: keep grass trimmed, reduce brush piles, and remove dense ground cover
Trap responsibly: use live traps in active areas, bait with peanut butter, seeds, or nuts, and check traps frequently
Relocate only if legal: follow local regulations for trapping and relocation; otherwise use approved control methods
Use repellents: apply chipmunk-safe commercial repellents labeled for chipmunks; reapply as directed after rain
Try plant-based deterrents: use products containing castor oil or similar repellents labeled for chipmunks
Protect specific plants: use cloches/cages over seedlings and wrap bulbs with wire mesh
Deter with motion-activated devices: install motion-activated sprinklers or lights near entry points
Remove nesting sites: clear leaf litter, stones, and debris near structures
Consider professional help: contact a licensed wildlife control operator for inspection and removal
Prevent re-infestation: after exclusion, keep monitoring and seal any new holes immediately
