Many years ago we used to drown the litttle buggers...Bucket 1/2 full of water, ramp up to the side and sprinkle wheat on top. Mouse runs up the ramp & plop, into the bucket.

Was doing some work in Moonie some years ago and that was the method we used. Sleeping in the shearers quarters we had about 10 buckets and they where everywhere. As you came in and turned the light on the floor started off grey and then turned to white eventually.
As far as sleeping went, in the end you got used to sleeping with a sheet over your head and wrapped up like a mummy. The feeling of them crawling over you at first is not the best thing, but after a couple of nights without sleep and big days at work in the end the body gives up and you sleep.
The cold weather slows them down quickly.
