I have looked for footprints, but this bog area is all built up organic matter and just to rough to see any, I have looked for scat all over and can't find any sign either. I am beginning to think it is more like raccoons because normally the armadillos do a much more destructive job of digging, and I don't think they could get under the netting with out leaving a visible entry. The area is backed by a field and woods area, so it is very possible it could be raccoons or any of a number of critters. I did recently find some scat in one of my flower beds inside my fence I did not recognize and some similar (light duty digging) I took a picture don't know how well you can see it, let me know what you think.
I was not clear about the location, the fenced in area where the scat was found was inside my chain link fence, not the deer fencing around the newly planted daylilies, about a couple of hundred feet away I would estimate.
