i have used barefoot and i guess it was good. i hear good things about humaworm, too. i guess its who and what youre most comfortable with doing. i know if you take enough black walnut that those buggers will make a beeline for the exit. i was playing with black walnuts one summer and dumped some water on yard. boom, earthworms came shooting out of the ground like missiles from their silos. then they danced around on top of the blades of grass to try to keep away from that black hull water. wow!
