I trapped a live mouse and dont know how to release it without killing it?

Try to slide a flat bottom under the container, and then just pick it up.

My mother released a wild mouse she found. But it was easier for her because the mouse had found its way into a small compost bin and my mum just picked up the bin and upended it in a nearby field. You could try peanut butter on a trap

slip a piece of cardboard or thick paper and flip over the case. release in neighbors yard.
