All I know is I give snakes one chance to seek life elsewhere, and then I get out the snake bashing club. When I discovered a rat snake behind the board I put up over one of my windows this hurricane season, I found me a stick, picked him up, and put him in the bushes where he belongs. He showed no inclination to do me harm, so I helped him on his way. Had he turned on me, I'd have splintered his carcass, and given him what Marv calls the hard goodbye.
