Exactly how long (how many days) since you brought him home? Always best to do NO handling (or touching) for the first 2 weeks, while they settle in-
and even better to wait until a snake has fed easily at normal intervals for 3 times, which would mean leaving them alone for about a month (if a young
snake that's eating about once a week).

It's no fun having a terrified pet, & no fun for them to bite in self-defense either. Remember to put yourself in his place...his instincts tell him the only thing
that picks him up is a predator about to have him for dinner! Snakes DO learn otherwise, but we need to be patient & put their health & welfare first.

The hide on the left in photo is probably fine* but the one on the right doesn't count as a hide, only as cage furniture to climb on. For best results, snakes
need 2 hides, one warm side & one cool side. The one on the right is FAR too open & offers no ability for a snake to hide.

*Hides should not be too much taller (inside) than the snake (when curled up inside) as they prefer "back pressure" (feeling snugged-in), and the doorway
should be just slightly bigger than the snake (with a bulge from a meal). If a hide is too big but not radically-so, you can crumple up a paper towel or 2 &
stuff inside for the snake to feel safer, but the "hide" on the right is, well, hopeless. (lol)

When you offer better cage security (from your snake's viewpoint) it should help him settle down, which is what you want, to keep him eating & also so
you can progress to handling.
