Face rubbing

I brought home a new BST python on Saturday, and she's currently in a different room doing quarantine. I noticed yesterday that she was rubbing her eyes and nose all over her body and the glass, but she stopped after a while so I just wrote it off.

Today after I was done feeding my 5 year old male BP he also started rubbing his face on his water dish and hides. Like hard. I haven't broken quarantine, but I really think these occurrences must be related. Someone else must have broken quarantine when I wasn't around.

I haven't noticed any wheezing coming from either snakes, but the BST has been breathing a bit heavier than I would like. I'll be keeping an eye on both of them just incase it ends up being a RI.

What else should I look for? Neither have been soaking in their dishes, but could mites be a possibility? Any input is appreciated, thanks.

Face rubbing is usually how they start to shed, but it could be stressed out too.
Is the snake acting frantic or just pushing hard on it's nose?

Just pushing hard on his nose/eyes. The baby girl was pushing on her own body and all over her head, including the top of it. It was actually pretty comical watching her scratch the top of her head on her back.

My BP hasn't shown any signs of shedding yet, and he shed just a couple weeks ago. The BST is 6 months old, and her's might be related to stress. I'm just concerned because I haven't noticed this behavior before, and they happened back to back.

edit: I'd like to add that the temperature in the Borneo's tank was a bit too hot, but I took care of that earlier today.
