Right now, I have noticed a large amount of dried corn left in the fields. I would get a few ears from the field, crack up the kernals of corn and use that as bait. I can also dig up worns and place them under such a trap, using fish hooks, fishing line, and twig anchors; as well.

Necessity is the Mother of Invention and when a need arises, a solution will be created or found.
