How To Get Rid Of Chipmunks – Installing Motion Activated Sprinklers

Chipmunks are persistent diggers, but a barrier of hardware cloth buried along fences can block their entry routes. If you’re wondering how to get rid of chipmunks, you’re not alone—these small rodents can wreak havoc on gardens, foundations, and patios. They dig extensive burrow systems, chew through wiring, and steal birdseed. This guide offers practical, step-by-step methods to remove them humanely or effectively, depending on your situation.

Chipmunks may look cute, but they cause real damage. Their burrows undermine sidewalks, retaining walls, and even building foundations. They also spread diseases like leptospirosis and salmonella. Acting quickly is key to preventing a full-blown infestation.

How To Get Rid Of Chipmunks

Before diving into removal methods, understand that chipmunks are protected in some areas. Always check local laws before trapping or relocating. The most effective approach combines exclusion, habitat modification, and deterrents. Here’s a complete breakdown.

Identify Chipmunk Activity First

Look for signs of chipmunks before taking action. Common indicators include:

  • Small, clean holes (about 2 inches wide) near foundations, rocks, or woodpiles
  • Mounds of loose dirt around burrow entrances
  • Missing bulbs or seedlings in your garden
  • Birdseed disappearing quickly from feeders
  • Chewed wires or insulation in sheds or garages

Once you confirm chipmunks are present, choose your removal strategy based on the severity of the problem.

Exclusion: The Most Reliable Long-Term Solution

Exclusion prevents chipmunks from entering your home or garden. This method requires patience but works best over time.

Install Hardware Cloth Barriers

Hardware cloth is a heavy-duty wire mesh. Use 1/4-inch mesh to block burrow entrances and fence gaps. Bury it at least 12 inches deep to stop digging underneath. Extend it 6 inches above ground to prevent climbing.

  • Dig a trench along fences or building perimeters
  • Cut hardware cloth to size, leaving extra length
  • Bend the bottom 6 inches outward in an L-shape to deter diggers
  • Secure with landscape staples or stakes

Seal All Entry Points

Chipmunks squeeze through gaps as small as 1 inch. Inspect your home’s exterior for cracks, holes, or loose vents. Use caulk, steel wool, or expanding foam to seal openings. Pay special attention to:

  • Foundation cracks
  • Gaps around pipes and cables
  • Door and window frames
  • Vents and crawl space access points

Habitat Modification: Remove Attractants

Chipmunks thrive where food and shelter are abundant. Remove these elements to make your property less inviting.

Eliminate Food Sources

  • Store birdseed in metal containers with tight lids
  • Clean up fallen seeds and nuts regularly
  • Remove fruit and vegetable debris from gardens
  • Secure trash cans with locking lids
  • Avoid composting meat or dairy products

Reduce Shelter Options

  • Stack firewood at least 18 inches off the ground and away from structures
  • Trim bushes and shrubs to reduce ground cover
  • Remove rock piles, brush piles, and dense vegetation
  • Keep grass mowed short

Natural Deterrents And Repellents

Some homeowners prefer non-lethal methods. While results vary, these options can help discourage chipmunks.

Scent-Based Repellents

  • Spread cayenne pepper or chili powder near burrows
  • Use predator urine (fox or coyote) around garden borders
  • Apply garlic spray or peppermint oil solutions
  • Place mothballs in burrows (but avoid near pets or children)

Note: Rain and watering wash away scents, so reapply frequently.

Ultrasonic Devices

These emit high-frequency sounds that may annoy chipmunks. Effectiveness is debated, but some users report reduced activity. Place them near burrows and change positions weekly to prevent habituation.

Trapping: Effective But Requires Effort

Trapping is a direct removal method. Use live traps for humane relocation or snap traps for quick dispatch. Always check local regulations first.

Choosing the Right Trap

  • Live traps: Wire cages with a trip plate. Bait with peanut butter, sunflower seeds, or nuts
  • Snap traps: Similar to mouse traps but larger. Place inside a box or tunnel to protect non-target animals
  • Body-grip traps: Use with caution; these kill instantly but can harm pets if not placed properly

Trapping Tips for Success

  1. Pre-bait traps for 2-3 days without setting them. This gets chipmunks comfortable
  2. Place traps along known runways, near burrows, or under cover
  3. Set traps in the evening when chipmunks are most active
  4. Check traps every morning. Relocate or dispose of captured animals immediately
  5. Wear gloves when handling traps to avoid leaving human scent

What to Do With Captured Chipmunks

If using live traps, relocate chipmunks at least 5 miles away in a suitable habitat. Release them near a wooded area with water sources. Never release them on someone else’s property without permission. For snap traps, dispose of carcasses in sealed plastic bags.

Professional Pest Control Options

If DIY methods fail or the infestation is large, call a licensed exterminator. Professionals use exclusion, trapping, and sometimes fumigation. They also provide warranties for follow-up visits. Costs range from $200 to $600 depending on the severity.

Prevent Future Infestations

After removal, maintain a chipmunk-proof yard. Regular inspections and upkeep are essential.

  • Reapply repellents monthly during active seasons
  • Check for new burrows weekly
  • Keep vegetation trimmed and debris cleared
  • Repair any new cracks or gaps immediately
  • Install motion-activated sprinklers to startle intruders

Frequently Asked Questions

What Is The Fastest Way To Get Rid Of Chipmunks?

Trapping with live or snap traps is the fastest method. Bait with peanut butter and place traps near burrows. Check daily for results.

Do Coffee Grounds Repel Chipmunks?

Some people report success using coffee grounds around plants. The strong smell may deter chipmunks, but it’s not a guaranteed solution. Reapply after rain.

Will Mothballs Keep Chipmunks Away?

Mothballs can repel chipmunks due to their strong odor. However, they are toxic to pets and children. Use sparingly and never near food sources.

Can Chipmunks Damage My House Foundation?

Yes. Chipmunks dig burrows under foundations, which can weaken structural integrity over time. They also chew through wiring and insulation.

Is It Legal To Kill Chipmunks?

Laws vary by state and country. In many areas, chipmunks are considered nuisance wildlife and can be trapped or killed. Always check local regulations before taking action.

Final Thoughts On Chipmunk Control

Chipmunks are determined, but you can outsmart them with a combination of exclusion, habitat changes, and trapping. Start with the least invasive methods—like sealing entry points and removing food—before moving to traps. Consistency is key; chipmunks will return if you leave any attractants or gaps.

Remember, patience pays off. A single chipmunk can produce two litters per year, so early intervention prevents a larger problem. Use the steps outlined here, and you’ll reclaim your yard from these persistent diggers.

If you’ve tried everything and still see activity, consult a wildlife professional. They have tools and expertise to handle tough cases. With the right approach, you can enjoy a chipmunk-free home and garden.
