Two links for you:

First, our CARESHEET ...which details how best to set up a first-time enclosure and what environmental settings to aim for. It also has a section called "Why won't my snake eat?" Which may give you some helpful angles to consider.

Second, a HELP FORM with specific questions that you can answer. The more of these you can answer, the easier it will be for us to help you dial in and fix the issues that might be wrong.

But read that Caresheet carefully first...use it to make adjustments to your enclosure, and see what happens.
