i'm sure you could get some good advice, with dealing with a currently aggressive snake, on here. i would just take a thick magazine and lower it into the enclosure in front of him, see if he strikes (make sure there is not way you can get tagged) and if he doesn't strike or if there is an opening, grab him behind the head and take him out with another hand supporting the body. That's how I put stuff back in my girlfriend's rtb enclosure when she is in her feeding instinct and mice smell is everywhere.
