Getting rid of chipmunks humanely can be a challenge, but there are several methods you can try that don't involve harming them. Here are some options:
Exclusion Techniques:
-
Seal entry points: Chipmunks can squeeze through surprisingly small openings. Carefully inspect the exterior of your house, foundation, shed, and other potential entry points for cracks, holes, or gaps. Seal these openings with caulk, wire mesh, sheet metal, or other appropriate materials.
-
Close up windows and doors: Make sure windows and doors close securely and don't have any gaps around the edges.
-
Chimney caps: Install caps with a fine mesh on chimneys to prevent chipmunks from entering.
Repellents:
-
Natural repellents (mixed success): You can try scattering around chipmunk deterrents like mothballs (use caution and keep out of reach of pets and children), castor oil, or peppermint oil. However, the effectiveness of these methods can be variable.
-
Commercial repellents: There are commercial repellents available that might be more effective. Look for ones containing predator urine or capsaicin (pepper). Always follow the product instructions carefully when using any repellent.
Habitat Modification:
-
Remove food sources: Chipmunks are attracted to food sources. Keep your garbage cans sealed tightly, clean up any spilled birdseed, and avoid leaving pet food outdoors.
-
Clear brush and debris: Remove any brush piles, woodpiles, or other potential nesting areas close to your house. This will make your property less attractive to chipmunks.
Trapping and Removal (last resort):
-
Live traps: If other methods fail, you can try using live traps to capture the chipmunks. Once trapped, you can then relocate them to a suitable habitat far away from your property. Important note: Check your local regulations regarding trapping and relocating wildlife, as there might be specific permits required.
-
Professional wildlife removal: Consider hiring a professional wildlife removal service if the chipmunk infestation is severe or you're uncomfortable handling the removal yourself.
Here are some additional things to keep in mind:
-
Be patient: Getting rid of chipmunks takes time and persistence. Combine several methods for better results.
-
Safety: Be cautious when using any repellents or traps, and follow safety instructions carefully.
-
Respect wildlife: The goal is to deter chipmunks humanely, not to harm them.
-
Local regulations: Always check your local regulations regarding wildlife control methods to ensure you're following the law.
By implementing these strategies and prioritizing humane methods, you should be able to discourage chipmunks from taking up residence in your property.
