If you're still having a problem with armadillo tearing up your yard try a product called Shake Away. It's powdered coyote urine you sprinkle around. I "had" a problem with armadillo too but I don't anymore. It also scared the squirrels, they no longer dig up bulbs I have planted. They think there's some huge predator lurking around.
Another thing you might want to do is spray your yard for grubs. That's what the armadillo are looking for!! If you do both things I mentioned I'd feel pretty confident you won't have a problem anymore!!
Having a problem with raccoons. Read about a fence with the top of the chicken wire hanging down, but the article didn't say how far the excess wire should hang down, or how tall the fence should be, and what is done at the corners of the fence. Any advice would be greatly appreciated, and pictures if available.
