My big brown hole, let me show you it: Before you ask, he's not in there at the moment, and I'm filling the whole with water (as suggested by my neighbour) to make him think he's dug into a spring or something so he fucks off. But I did that about a week or so ago and it didn't seem to work. So next I'll be filling it with large rocks, dirt, half a bag of cement I have lying around, etc. But my question is, how do I discourage him from simply building somewhere further along under the deck? Short of hanging around my deck with a large dog and a shotgun etc.
