Since we've moved in, both Prairiewolf and I have occasionally seen a hole that looked suspiciously like armadillo work. We've known that they are here, but they don't seem to be present in the numbers found further south, so we've assured ourselves that the hole probably wasn't actually made by an armadillo and moved on with life.
Well, all of those holes probably were made by an armadillo. Proof that we have (had) at least one resident armadillo is currently lying dead in the ditch in front of our house, a victim of a run-in with a car.
I normally mourn when a wild animal tragically meets its end, but in this case I feel more like celebrating. I want to be able to assume that we're done with armadillo damage for a while, but logic tells me, "Where there's one, there's plenty more."
Bah! Humbug! That was one garden scourge I was truly hoping we'd not have to deal with here.
