Chipmunks generally feed on nuts, seeds and fruits. Pumpkin seeds and sunflower seeds are effective seed baits. Plum or prune slices and raisins are good fruit baits, and even plum pits will draw chipmunks' interest. Chipmunks also love peanuts -- especially peanuts in the shell, either roasted or unroasted.
Bait humane traps with sunflowers seeds, peanut butter or raisins and place them in areas where there has been chipmunk activity. Check your local laws before trapping to learn if and where you are allowed to release trapped animals.
