If it was in my yard I'm afraid I would have to kill it. I hate killing anything and even pick up worms and put them back on my lawn after it starts drying out from a rain but a poisonous snake is a different story. If it were not poisonous I woulnd't care if it was there, as it couldn't kill anyone. My kids and pets take top priority and there is nobody to call here to get rid of it. If I waited for someone to come and get it (not even sure who around here would), I could risk it wandering off into someone else's yard and killing their children or pets. I wouldn't risk being bitten and possibly dying or losing an arm to save the snake. I would hate to do it but I'm afraid in that instance I would have to. We have had many other types of snakes in the yard and they don't bother me, I think snakes are awesome, but not poisonous snakes in my yard.
