I once rented an old wooden hut which was infested with mice. I tried several mehods, but the best result came with glue traps. I know some people don't like them as they seem to be cruel, but I just want to catch and kill as many as possible in the fastest time. I rather have a mouse suffer a bit then catch a terrible desease myself.
It said in the instructions to put the bait in the middle, and "dispose of the trap when full".
My girlfriend at the time always used to get rid of the traps when not full - but the whole purpose of the trap is that a mouse that is trapped is crying for help, and other family memebers come to investigate...works very well. I managed to catch 18 mice in a very short time.
Does not work with rats though. We once placed a few of these traps with a piece of Salami in a hut in the middle of an orchard, when we came the next morning the rats stole the bait, und in a clear act of defiance nibbled the glue traps themselves around the edges
We had to use poison on these....
