I've caught the odd mouse in them, what amazes me is how they mostly are smart and quick enough to pinch the peanut butter bait and escape! They either figure out how to open the gate or they are just quick. Maybe they do it in pairs, taking it in turns to hold the see saw up so the gate won't shut? Once you do finally outsmart them you've got to transport them to a neighbour's place at least 500 metres for release or they return next day. Brain power is not proportional to brain mass.
I use the earlier version of them, a blue rocker box with a yellow lid, only I've put a few small air vents in it so they don't suffocate.
I've put spots of tipex on their backs because I was sure when I dumped them out in the front yard they beat me back to the house. Well,.. not quite, but I did get many happy returns, and yes, you do need to put them about 400 to 500 metres away before they didn't come back.
I think even at that distance they try but either lose their way or something eats them on the trip back.
The strange thing is, they are smart enough to find their way back but not smart enough to remember they got stuck in the trap, so they just do it all over again.
I think they must think it's some sort of teleporting pod with in flight free food.
Beam me up Scotty.
Make sure you use gardening gloves if you want to mark them because they sink their little fangs right into your finger.

And throw a rag over them while you pick them up otherwise they run up your arm and onto your head.
