Drill a 4cm hole in a door along with 4x 3mm holes Install one mouse funnel mousetraps at the bottom of that door, with the pointy bits facing outside Put a box/container with peanut butter in it on the other side of that door Put the second mouse funnel mousetraps in the box/container, with the pointy bits facing outside Wait for the mouse to leave
