Claire take no notice of the man from the council laughing at you - we caught a couple of mice in humane traps. You do have to make sure that you take them a long way off to let them loose - you don't want them back do you. It is all very well them saying that you have to poison them but they take the bait and then die elsewhere - the man from the council told us that there would be " a bit of a smell" all I can say is - his bit of a smell was my idea of purgatory - it stank the house out and it was almost impossible to find the body (it was behind the bath panel)

Try Tina's peanut butter bait in a humane trap, but remember that they don't come alone they almost invariably bring their families with them so it will take a while to get them all. I found the way they were getting in and filled it with a spray can of expanding foam.
