Please help! My snake soak in water bowl again...mites come back?

[Phillydubs]

Thank you so much for your reply! The humidity is so high and I actually plan to drill more holes in the tub and the temperature is 80F low and around 87F high. He didin't soak this morning but I checked another ball python he got dark spots at his chin and back, I rub it with reptile spray on my hand and paper towel and they don't move or fall, like they're two-dimensional not three dimensional. He never soak I hope I'm too sensitive And may I know that how does the vet check the mites? Did the use some special tech or just watch it carefully?

Are these your normal temps and levels or have things gone up?

I personally would drop that low temp to 76-77... My Caye Caulker boa likes to thermo regulate, my dumerils boa 90% of the time prefers the cool side and he likes it cool. I have a feeling as the other poster said that the sanke is trying to cool itself because it is just too hot. If you have a hot spot leave that in the upper 80's the rest of the tank can be kept cooler, if the snake wants the heat it will find it trust me, but you aren't giving it much of a choice right now. Try to lower it and see what happens.
