Can I ask what would do you think would happen if Andrew put a flagstone or big rock on the top of the hole? Would it tunnel and appear outside the GH?
I had a hole but much smaller in my flower bed, I poured water down and it took half a can, then I filled with soil. Next morning same hole I continued and then a few days later saw a mouse. I put bait down the hole and put a big stone over the hole. No more holes appeared and I was able to refill the hole and it's been okay...
However mine wasn't a rat and not in with my edibles
