Please don't abuse this knowledge, don't be an idiot and kill without reason.
you can use this type of trap with a box or crate instead of a deadfall and simply catch the animal.
this trap is better than the figure 4 deadfall because is is easier to set, has a more sensative trigger, and your hands are safer when setting it.
Step 1: Gather Materials
-a small length of cordage
-two sticks equal in diameter (about) one stick about 8 inches, and one stick about 6.5
-a long skinny trigger stick
-and a 3 inch toggle, a little fatter than your trigger stick
-a deadfall or box
-(extra weight if necessary i.e. bricks etc.)
-good sized sharp knife
Step 3: Set up, step 1
Step 4: Set Up Upright and Deadfall
okay, make sure that you put your upright in the ground at an angle, and maybe bury it in the ground like 2 inches. also make sure that your ground is hard, or you put plywood under where the deadfall will fall.
make sure that the underside of your deadfall is rough, like a piece of granite, or if your using wood like me, take a nail or a knife, and put lots of parallel deep cuts (almost notches) every cm. or so... these will be there so that the trigger stick will be able to stick up against it. make sure that the ground under your deadfall is hard and LEVEL!!!
