I can't say for certain if he will bite or not, you basically just going to have to try it unless you want to invest in a snake hook. All of my BPs are in tubs, but a few still like to act like they are going to bite me. My boa does what your BP does and will follow my hand sometimes. So far she hasn't bitten me, but it does freak me out a little. With her I just go slow and she seems to accept me. You could also try distracting him to draw his attention away from you hand. I do that with my sister's rat snakes. I take a paper towel roll and draw there attention away with that before I pick them up. Most snakes in my experience are fine once you get them out.

I hope this helps, good luck!
