Ziggy nailed it especially with the caging questions (split it).....carpets are nippy babies typically. I hold mine literally every day during the hatchling stage to get them out of their habits. Just remember they're never going to be able to do as much damage to you as you can do to them. Most will grow out of it within a few months.
I personally, do not use any sort of tool with my carpets to retrieve them when they're babies...instead I just get them used to being picked up but I do hook train my Burm that I have which is a completely different story all together.
