Trespasser back blip

When we arrived I noticed the sunken garden by the front was all but destroyed. I really thought a cow had been in there. Everything crushed, eaten and dug up. Well, I was washing dishes and looked out the window to see this varmint tearing up what was left of the asters. Hubby discovered it has dug a hole under our cement porch and may be living under our basement. That will not work. This is the porch to our front door. We put mothballs in the hole hoping he will leave. WHY? I made apple blocks and painted some more on the yard art.
