RE: Weasel trappng
Never tried just for weasel, any I ever caught were by accident. Couple ways told me were to nail a chicken head or similar to a fence post and place a trap under it. Other was to make boxes out of wood with 1 1/2"-2" holes in either end. Place traps inside of box under each enterance hole and bait in the middle. Fresh, bloody bait is best I think. I'm sure others have better ones. Good luck.
