BTTT
I've had cheese stolen from the trap. Peanut butter they lick at and keep trying to get more until it finally snaps.
Hints from Helouis, (SP?), years ago, said peanut butter, and my experience says it works.
The mice stole the cheese. When the cheese was tied on with thread, they nibbled the cheese off until it fell free from the thread binding it onto the trap. Moved on to using peanut butter, but they simply licked it off of the trap without springing it. Frustrated, I put cheese bits and chunky peanut butter into a scrap piece of nylon hosiery, tied it closed with thread, and tied the bag onto the trap. Twenty minutes later...SNAP! Reset the trap...and SNAP again. Reset the trap....
