Fuck these little tunnel rats! I've tried poison bait, gassers, traps (no, not that kind but at this point I'm open to anything), gunpowder, deterrent plants, just about anything that won't land me in prison or taint the water table.

Anybody found anything that works? I even tried uncovering their holes and waiting with a gun. I'm out in the country in a part of California where they leave us alone. I'm willing to try just about anything.
