I've tried having him go over the paper towel many times but those ones are truly stuck.

Also, because I don't want to open another thread and annoy people, I was seeing if I could remove the mites with a soft toothbrush/the piece of paper and they just don't budge - I'll be trying a second treatment of the spray today/tomorrow with paper towel again to see if that'll get rid of them under his jaw.

The second issue is, when I was holding him today to try and get the extra mites off his jaw, I noticed his belly coloration was different - I'm not sure if this is scale rot or some other thing (ignore my messy desk and tons of money):



I know scale rot needs to be kinda a rusty color so it doesn't look like this and this did happen overnight practically.

Now what I think it is, is when I cleaned his tank on Tuesday, I woke up on Wednesday to find feces in two corners of the tank and poop smeared everywhere. It was very rude, lol. So I'm assuming that is due to his smearing it all over his tank like the filthy beast he is. By the way it looks, it looks like it could be that. I've never left his substrate wet before except when he went overnight and part of the paper towels were damp from his mess but that couldn't have been more than 6 hours and he wasn't on that side when I found it.

My substrate is paper towels with 55-57 humidity and hotspot of 90, with cold side of 82 and ambient 83.
