My Antaresia are the same - they're active and curious, which I love. One thing you might try for your little guy is one of those pet 'playpens'. Not the metal kind, but the cloth + cloth screen type. Just search 'pet playpen' on Amazon. I have a large and a medium sized one that I use for my snakes when they want out to explore but I am needing to do other stuff and can't supervise them directly. The playpens have a screen top that can be zipped shut - I toss hides, branches, cardboard boxes, plushy stuff or towels (they love soft materials), fake plants, and other enrichment items in there. The playpen can easily be folded up and stashed away when not in use.
Those things have really been a help for me, as I have a few snakes that love to come out, and I always felt terrible if I was busy and couldn't let them out.
