Lapkritis: Agree about the poison; definite no. Several years ago had poison in mouse sized plastic dispensers around my garage and an energetic chipmunk chewed into the device and ingested all the poison, then crawled around my garage and died under my Porsche. Could not locate until it smelled to high heaven and it took several days. God knows what happened to the mice that died.

What do you mean by baitless traps? Are these enclosed devices? What would make a mouse enter such a trap? Photos would be nice.
