I keep getting the little so and so's in the utility room Ronnie - I phoned the council and they recommended some poison (can't remember the name but it is little blue grains) and to block any gaps with steel wool as they can't chew through that apparently. I'm not sure I believe him as they keep getting back in every few months.
I did try the humane mouse traps but couldn't get rid of them, the chap at environmental health laughed at me and said the only way is to poison them. I feel really guilty about it though as they are sweet little things
