Last Saturday we went to Tractor Supply and decided to try giving them the gas chamber before poisons or snap traps. I got these "rodent smoke bombs" but the weather was too lousy to try it out, then I was home sick from work for a couple of days. Hopefully I will be able to give a test run on some holes Saturday. I set up a "smoke gun" as I didn't want to burn my sheds or shop down with the burning weapon!
Appearantly, the woodchucks in California are immune to the stuff
