RE: Today I Learned How to Build a DIY No Harm Mouse Trap
How clever! In case it's not obvious to anyone, the trap is amazingly simple in its operation. The mouse climbs up the pedestal and enters the bottle. As it enters its weight causes the bottle to pivot, so the opening is blocked by the pedestal so it can't escape. Make sure you minimize the clearance between the bottle and the pedestal so the mouse can't squeeze out between them. I've read that mice have squeezed through openings as small as a pencil!
Ah damn! I think the power of my cardboard might not be enough to hold off the mice... they can probably get their nose or claws into the open space and push the frame back enough to squeeze out. I guess that's why the original video has it made from a metal clothes hanger... hehe. Well so far no luck in catching anything. Cracker still there. But yeah, a great design.
