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.
