You can take the following precautions to prevent chipmunks from producing problems around the foundation of your home if they are already doing so:
Chipmunks are drawn to regions where they can obtain food, water, and shelter, therefore it is important to get rid of anything that might attract them. Take the necessary efforts to remove these potential drawbacks. Chipmunks can be deterred from an area by removing any food sources that are easily accessible, securing garbage cans, and cleaning up any fallen fruits or birdseed that may have landed on the ground.
Inspect the foundation of your home for any cracks or openings that chipmunks could exploit to get inside. If you find any, make sure you seal them up. Caulk or any other material that is appropriate should be used to seal these openings to prevent these pests from entering. Pay close attention to the regions around vents, pipes, and entrances to utility services.
Chipmunks have a habit of digging and burrowing in gardens, therefore garden maintenance should account for this. It is important to keep your garden in good condition by clearing away any waste, dead leaves, and excess mulch on a regular basis. This will prevent chipmunks from using these things as places to hide. It might be a good idea to block access to susceptible garden areas by erecting a wire mesh or fencing around them.
Utilise Natural Deterrents: There are a number of natural approaches that you may use to keep chipmunks away from your property. These are the following:
Planting Deterrent Plants Certain plants, like daffodils, marigolds, and garlic, have natural repellent characteristics that chipmunks do not enjoy. These plants should be planted in areas where chipmunks are a problem. They can be discouraged by planting them along the perimeter of your home’s foundation.
Chipmunks have a highly developed sense of smell; therefore, utilising items with a pungent odour can be an effective way to discourage their presence. If you want to discourage their presence, you can try sprinkling mothballs, chilli pepper, or predator urine (which you can find at garden centres) near the entry points they use.
Spraying repellents can also be an effective method. There are commercial repellents that are created expressly for chipmunks. When applying these products, make sure to follow the instructions very carefully, as it is possible that some of them will need to be reapplied after it rains.
Install Physical Barriers: If the other measures do not work, you should think about installing physical barriers in order to prevent chipmunks from entering the area around the foundation. Installing wire mesh or hardware cloth around the perimeter of the house, burying it a few inches below the ground, and extending it a few feet above the ground to inhibit digging is one option for accomplishing this.
Humane Chipmunk Trapping and Relocation If the chipmunk activity continues and becomes a severe nuisance, you may decide to humanely trap and relocate the chipmunks by employing humane live traps. Check to see what the local restrictions and procedures are for relocating animals and catching them in your area. After you have captured the chipmunks, set them free in an appropriate area that is quite a distance from your property.
Keep in mind that it is essential to take into consideration the local rules and regulations pertaining to wildlife control, as well as to select techniques that are both safe and humane. If you are unsure of what to do or are dealing with a chipmunk problem that does not seem to be going away, it is recommended that you get assistance from a professional pest control or wildlife management firm.
