I had a scrubby that was very bitey (who knew hey)... I found that slowing down my movements only gave him a better look at what he was looking to bite, and when walking past his enclosure, it was done at a normal speed, so should all movements when placing limbs in the enclosure. I used normal speed, deliberate movements and he soon stopped tracking me ( reasons unknown but it worked for me ) I also used and continue to use a hook, which can upset him if he doesn't want to be picked up, but it gives a bit more room for error. If when attempting to hook him (Hannibal) and he looks like he's not in a good mood, I leave him for an hour or two. This technique of reading his behaviour before attempting to interact with him, seems to have saved me from losing copious amounts of blood.... I also allow him to venture from his enclosure before hooking and handling which works pretty well....
