I used a minnow trap to cetch the snakes around my pond. Frogs and tadpoles will enter the trap on accident then the snaks will go after them and not be able to get out. By leaving 1/2" of the trap out of the water the frogs can breath and not drownd. Its cruel and it kills the froges but I killed 4 copper heads in 2 weeks without spending much time waiting to see them to shoot.
