I saved a copperhead from a neighbors shed a while back - scooped him up with a pitchfork, kicked a plastic bin under him, and dropped him in. I relocated him to a large drainage area of several acres thick with poison ivy where he will be quite happy. He was not at all aggressive but his heat sensors let him track my every move in a disconcerting way. I got a couple close up photos when he stuck his head around the corner of the box because I was sure he could not strike around corners.
BTW, some animal are resistant to snake venom including the American possusm and the African honey badger, who of course doesn't give a shit..
