mine does it too, when i first got him on dec. he would strike when ever i open the cage to handle him, since using a snake hook is useful tool to get the snake out but first rub it on the snake body to let him or her know its you and take him out gentle, let him sit on your lap or hand and dont make any sudden movement, dont use the snake hook the day you are feeding him also dont use the hook while you are feeding him. other trick is to put the snake in a snake bag or a small pillow bag and while the snake are in the bag you hold it on your lap or in your hands rub the snake while he is still in the bag. sometimes it take a while for the snake to settle down it took my burm to settle down less than 1 month and he is great now. dont forget to leave your snake alone for 2 or 3 days after eating the meal. hope this help.
