Thank you so much for replying. I’m sorry for the length and format of my post and I’ll space things out better in the future.
That being said, yes I was extremely surprised that the snake had mites. I may have expected that from a snake from petco or pet smart or whatever, but the store I went to had great reviews online and I know three people who got their animals from there and they had nothing but excellent things to say. Anyways, what’s done is done.

For treating the mites, I used Natural chemistry Reptile spray. I was thinking about using diluted ivermectin or PAM, but as my snake is very young(under 3 months old), I was worried about those treatments being to strong/harsh.

Anyways I sprayed a white towel with the reptile spray liberally and put in down on the bottom of a tub, placed the snake on the wet towel and then sprayed her directly from the neck down. Then I got a paper towel heavily saturated with the spray and gently wiped her head/neck area and left her alone for like 10-15 mins. Finally I sprayed a little bit on a cue tip and wiped her pits/nose area and then I soaked her in a tub of water at 90 degrees for around 20 mins(to drown any remaining mites and also to wash the chemicals off her).
Meanwhile I took everything out of her enclosure, threw away all wood, everything else first I sprayed with the spray including the tank itself. I made sure to spray into the corners and all over the inside and outside of tank and the surrounding area where the tank is kept. Rinsed the tank, and Then I used diluted bleach and sprayed the tank and her hides and water dish liberally with that and left for 15 mins and rinsed. then filled her tank all the way with HOT HOT water and soaked her hides/bowl in hot hot water for 30 mins. Then dried, and put everything back. Instead of cypress and moss, I put paper towels as substrate for a little under two weeks and added a humidity box with damp moss. I haven’t seen any mites since. However i did switch back to the cypress and moss substrate when she was having a hard time with shedding.

lastly, the shop told me she was eating a hopper mouse every 7 days, which I was following Every Saturday until this week. Starting this week I fed her a hopper on sat and again one on tues. which is why I found it odd she was still hungry on weds..
