A mouse in my house

For the last couple of days I have suspected that a mouse has been carrying out scavenger missions in my flat. These suspicions were founded on nothing more than a rustle here or there and largely I thought myself paranoid. Early this evening I found almost conclusive evidence of wee rodent activity when I lifted something up and found some shredded kitchen roll. Tonight however I have irrefutable evidence! About an hour ago I spotted the mouse (he really is quite cute...but that's beside the point) and promptly called in the male backup in the form of my friend at the hotel. Even luckier for me, my land lord had been manning reception this evening so the phone was promptly handed over to him. Both men rose to the occasion and set forth across the road to become mouse hunters supremo.....sort of. They failed to catch the mouse but my land lord saw him and that's the main thing because I am getting mouse defenses. The mouse disappeared and we eventually concluded that he had retreated into his own mouse house underneath the radiator. Lovely landlord blocked up the hole with a sponge and they both left.
10 minutes later I spot the little bastard crawling up behind the radiator, I watched like a hawk for a while and when he didn't emerge took a torch to the back of it.
There is another blasted hole above the one we blocked up about 4 inches above it behind the radiator which cannot be reached by hand.
I can only hope that tonight's adventures and lack of food in my flat deter the mouse for the night and that my mouse weaponry arrive soon.
