Aggressive kingsnake help

[Gypsyfreespirit]

I have a 5 yr old Brooke's Florida kingsnake, have had him since he was a hatchling.
First three years he was very docile and easy to handle, last two years...he's super aggressive and bitey. Attacks the cage when I come near and now I have to wear gloves and use a hook to remove him.
I use to feed him in a separate container but he got super aggressive when taken out so I switched to cage feeding about 3 1/2 yrs ago. I always drop the f/t small rat on the opposite side and feed him every 10 days.
Any ideas or help appreciated, I'm at the point I don't even want to take him out and am considering finding him a new home cause I just don't enjoy him anymore.
