Spring traps are awful! We had mice for a few weeks in The Bahamas until we found the hole in the ceiling and blocked it. We (well, my husband) would set the spring traps before we went to bed and the minute we turned off the light, PING would go the trap and my husband would have to get out of bed to find the mouse as the trap and the mouse had been propelled several feet away! It was awful and I was no help at all. Mice may look cute but, please, not in my home!
