Chipmunks are cute and fun to watch — until they begin eating your crops and digging holes in your yard. It can be difficult to rid yourself of an established chipmunk colony, however there are things you can do to make your yard less hospitable and encourage those woodland creatures to proceed. You may try out both humane and fatal removal methods based on your own personal preference and the size of your problem.
Eliminate any groundcovers, shrubs or other plantings that associate your yard to wooded areas.
Move bird feeders to an area of the yard where chipmunks won’t be a nuisance or remove this chipmunk food supply completely. Bird feeder should be 15 to 30 feet away from places you wish to keep chipmunk free.
Get an outside cat or permit your dog to be outdoors more often. Cats and dogs both frighten chipmunks, and an outside cat will hunt in addition to intimidate them.
Place mothballs every few inches around your home and garden. Drop five or five mothballs to any chipmunk hole you find in the yard and cover them with dirt. Use caution if children or pets are regularly in the region, since mothballs are poisonous.
Spray plants which the chipmunks are chewing on using a warm sauce and water solution to make the plants less appealing.
Bait humane traps using sunflowers seeds, peanut butter or raisins and place them in places where there’s been chipmunk activity. Check your regional laws before trapping to learn if and in which you’re allowed to release trapped creatures. Some municipalities may force you to euthanize rather than release them.
Set mousetraps or glue boards in areas where it’s safe to do so without fear of undermining the neighbor’s cat or other wildlife. Bait mousetraps with peanut butter only after a couple of days of baiting them without setting them. The chipmunk will not be as wary and easier to capture if it has gotten away with a couple of free meals already.
Fill a large bucket halfway with water. Attach a board from a retaining wall or other lifted landscape feature to the top of the bucket to create a plank. Sprinkle sunflower seeds across the bucket, about the board and in the bucket to lure chipmunks to the water trap.
