In regards to armadillo, they are vectors for chargas and leposry.
Also, if the above wasn't enough to warrant a well placed .22 LR the fact that the burroughing buggers can cause massive problems for livestock.
Same with gophers, those I don't know if I've ever actually seen a gopher round these parts.
Also, in the winter, it isn't unkown for a coyote to isolate a young calf or smaller cow and feast away.
My Big Sister 4-H prize winning cow met a tragic end to a coyote(s) when she was in middle school and I was in elementary school.
Pop and I hunted those things for weeks in effort to stop her from crying.
