Place bird feeders at least 15-30 feet away from buildings so spilled bird seed does not attract and support chipmunks. Landscaping features such as ground covers, trees, and shrubs, should not be planted in a continuous fashion connecting wooded areas with the foundation of the house. They provide protection for chipmunks that may attempt to gain access to the home. It is also difficult to detect chipmunk burrows that are adjacent to foundations when wood piles, debris, or plantings of ground covers provide above-ground protection. Reduce the attractive cover or nesting sites to discourage their reproduction.
Trapping is the most practical method of eliminating chipmunks in most home situations.
Trapping with wire mesh traps or common rat snap traps can be used to catch chipmunks. A variety of baits can be used to lure chipmunks into box traps, including peanut butter, nut meats, pumpkin or sunflower seeds, raisins, prune slices, or common breakfast cereal grains. Place the trap along the pathways where chipmunks have been seen. The trap should be securely placed so there is no premature movement of the trap when the animal enters. Trap movement may prematurely set off the trap and scare the chipmunk away.
