Bp stopped eating frozen

Hey guys, my ball stopped eating frozen for some reason. That's what I fed him for almost a year without fail, and then one day he stopped taking them and that was 6 months ago. Not a thing has changed in his enclosure and he will still take live or pre killed. Any thoughts?

Bps can be picky sometimes. They can eat frozen for x amount of then want to switch to live out of the blue. Mine have done it a couple times already. Just give him live if he wants live. Or u can try to trick him by warming the frozen up and then rubbing it in used rat bedding. Sometimes it works sometimes it doesn't. Best of luck.
