Ok it is possible that nothing is wrong that she has taken to digging. Or something could be wrong. Nice and wishy washey there.

Someone posted about the liquid crystal thermometers you have. First thing is they are more accurate then most digital ones on the market (0.5ºF error). The second thing is the placement is poor.

If you are getting 90º on the glass it is likely that the interior temps are quite high. Do you have a probed digital thermometer? If not one would be very useful. The stick on glass ones are very accurate but they measure the temp of what they are on, I'd not stick one inside as there is a chance of the snake managing to get it off and stuck on them selves. However if you do not have a probed digital one you could buy a new LC stick on one and use it not stuck on anything just placed in the hot hide and one the substrate on the cool side. Or pick up any digital probed one they all have the same specs and the chance of getting a good one is about the same.

What we are looking for are three temps.

The hot side on the substrate in or beside the hide.

The cool side on the substrate in or beside the hide.

(Did you say you had two hides or just one?)

The mid point between the hot and cool end about 3 inches off the substrate. Not touching the sides.

My guess and it is simply a guess they way you are measuring the temps is not very accurate basically you are checking the glass temp. I am guessing *GUESSING* that the temps inside are higher than you are expecting and that the snake is burrowing away from the heat to get to cool temps from the bottom of the enclosure. This is a guess but unless you are not in the norther hemisphere it is getting warmer outside and the ambient temps are getting warmer. That added to the lamp heat system may have pushed the temps from good to too hot.

Double check your temps using the method I described and lets see where we are.
