BP won't go into either of his hides

Hi, I'm new so sorry if this question has been asked before but I couldn't find anything. My BP Frost recently won't go into either of his hides. He has one on the warm side of his tank & one on the cooler side. The ambient temp on the cool side is about 80 & on the warm side, I have a UTH under that hide. It has a dimmer to control the temp (after I first got the UTH it was getting too hot & frost started not going in there) & the probe of the digital thermometer says the top of the substrate is about 92 (it feels a little cool to my hand so I wonder if frost feels the heat at all but humans run around 98 so maybe it's just cold to me). I put frost back in the warm one to show him that it's not too hot anymore, but now he won't go into either box. Why won't he go into his hides? The temps seem ok & there isn't poo or that white stuff in either of them. I just want him to be happy.

Also, I know the temp of the glass is warmer than what the substrate is. If frost does go in his warm hide & sits there for a while, will his body take in more heat from the UTH & get hotter than what the thermometer says?

as long as your temps are properly set, the snake will be fine. they know where they are comfortable. they are very efficient at picking the temps they need to properly thermoregulate...and they have for thousands of years. so if your temps are right, and from what you say, they are fine...then don't worry about it and let the snake hang out where it is comfortable. if you keep stuffing him in the hide, all you are going to end up doing is stressing the snake, and then you will probably have problems with feeding. an ambient(over all air temp) of between 80-84 degrees is perfect. a hot spot of about 88-90 is good, and you want to shoot for about 70% humidity. you don't really want the coolest part of the enclosure any lower than about 75-78. I have my hot spot at about 90, and that is on top of the substrate. it is about 112 under the substrate right on top of the heat cable...and I have several ball pythons that will burrow into the bedding, or go under the paper and sit right on the hottest part(112 degrees), and sit there for a couple of hours...and have never had a problem. I think you are fine where you are...just let the snake pick where he is the most comfortable.

I had a BP once that wouldn't use a hide. Ever. Just like humans, there's going to be the oddballs :P
