I ALMOST shot a chipmunk that was burrowing all over my back yard. I have a Remington 597 .22 long. Was going to just stick it out of a window and pop, its dead. Watched it run from the patio to its primary hole. I had read that really hot hot sauces make them go away too. So I put 1/2 a bottle of "Dave's Insanity Sauce" in a few cups of water and poured THAT down the hole. The stuff irritated my nose and eyes even outside before I dumped it down the hole. Never saw it again.
