Well I found some smoke bombs for killing gophers moles groundhogs so gonna try that first.
Put 2 down hole next to foundation dumped 1/2 wheelbarrel rocks over them and dirt on top.
Only see the one deep hole, saw couple other spots where he must have been diggin but they shallow.
I filled them in and sprayed coyote urine around them.
So hope I nipped him quick...just first saw hole yesterday.
Time will tell
