I've got a ton of black snakes around me...
see this thread:
I've only had to kill one copperhead since I bought my house. No gun... good ole' fashion shovel...won't do that again. Next time I'll shoot first, ask questions later. I generally leave the black snakes alone, I'll just move them (via long pipe) to somewhere else in the yard or sling them over my fence into the pasture that's around me. The black snakes help take care of the field mice and moles...so I'll keep them around.
