Our last summer place was a highly converted mobile home. When we first purchased it, we soon found out that it came with Mickey and many friends and relatives. It burned me up to be watching TV and have a tiny guest come around the corner and stop and look at me like he wanted me to change the channel to Mouse-TV. My wife dubbed it the "mouse-house" and the battle begins. A few cans of expanding foam later, we really got it under control. Fundamental warning: Poison/bait works great until one dies in the wall, or worse...the HVAC ducts...Oyyy! The glue traps are OK, but if they only stick one foot, they drag it around like a skateboard...usually happens in the middle of the night (you gotta thumb tack 'em down). We ultimately discovered the wisdom in not trying to re-invent the mouse-trap. The dollar store got good business.
