I've read hundreds of posts about how to control these guys. Swimming pool of death, elecric trap, rat trap, moth balls, kitty litter, humane traps with release, the list goes on and on.

Has anyone thought of gassing them with the auto exhaust at night? Plugging up as many holes as you can see at dusk, then running one of those hoses for auto garages off the exhaust into a small reducing bushing with 1 1/2" PVC and stuff it into the hole? hello a little CO when they are already sleeping.

Good idea or not?

Let them die in the ground...no removal, no suffering, no smell...
