As others have stated, for a captive bred ball python that is set up correctly, there is no real need to use something such as the rept aid.

To be fair, it can be quite effective with lizards, in particular chameleons, which it was designed for. I have seen numerous customers (as well as used it myself at home) with animals that have turned around after using it.

For your ball python, though, it's probably unnecessary.
