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
