Owning land can come with unwanted "guests". After having little luck catching big wood rats with traps I came up with this idea. It's like a rat trap garage, it covers the trap on the top and three sides so the rat can only enter at the business end of the trap. It's never been set off without having a rat in it. I use a shinny stainless steel wood screw secured to the bait plate and cut a little apple to screw onto the that for the bait.
