Effective chipmunk/ground squirrel control
PEANUT BUTTER. Make a little bag out of old nylons, or some other permeable material.(Cut a circle about 4 inches in diameter. Put about 1 teaspoon of peanut butter in the middle. Pull the edges together to make a bag. Wire it shut.) Smear PB on the outside of the bag for scent. Wire the bag to a rat trap so the chipmunk will tug on the bag to try to carry it away. Your bait will last a long time if you use this method. Mouse traps are too small but rat traps (the spring kind) work very well and are fast. The little guys don't suffer.
Chipmunks are cute until they rip out your house insulation, chew your electric wiring, destroy the insides of your car, build nests in your air filter, eat all your strawberries and snow peas, etc. . . And our cats don't control them.
