thanks to sparrow, who put me on, (or up?) to it, I have just caught one more mouse. That brings the number up to 8. No poison, no bait. (I have removed the chocolate, they go in the trap out of curiosity). Anyone with a mouse problem, here is the solution. Take them far away from the house, I have been thinking the local Shopping Centre or Mc Donnalds would be nice for them.
Easy to use, you "wind up, catch all", that's what the trap is called.
