The same method can be used with a safer gas such as CO2. Borrow a tank from
a friend who has one or rent it at your local supplier of CO2 (you might
have to go to a bigger city to find a supplier). CO2 is safe, heavier than
air, and non-explosive. You can use the remainder of the gas for fizzing
drinks, quick-freezing something. You do have to be cautious when using the
tank. As the compressed gas expands, the temp drops drastically and can
cause frostbite if not handled correctly, as can a fire extinguisher.

A few years ago I had several dens of them. What we call (groundhogs). I
took the LP tank, regulator and hose off of my gas grill and let it run
about 15 min. in each den. I should not brag but I haven't had a one
since. I think the LP stays down in the den. I had to do something
because they was making dens where I mow with the tractor and was afraid
I would end upside down in the creek.
