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.
Set the trap and let the chipmunk come inside to get the food. Do this for a couple of days so that the chipmunk is really comfortable going in and out of the trap. After the chipmunk has done this for several days, the next time you bait your trap, set the door so that the door will close after the animal is inside.
