King Snake being weird

I dont know how else to describe this behavior. She does this occasionally. She actually started doing this when I got her the hides...

EDIT: Crap I think she might have mites and she's scratching her head like this... She decided to take a dip in the water but no bugs seen. She's on paper towels but I don't see anything there or her water bowl... I guess PAM is in order.
Do king snakes go in their water bowl a lot? She does this like maybe once every two days. Stays in there for like a couple of seconds and goes about exploring.
Is there a place I can get Provent a mite that doesn't charge a million dollars for shipping or a different alternative?

Well I don't think she has mites anymore. She's been on paper towels for almost 2 weeks and no signs of mites. But she's still being weird. Is it because she has no where to burrow? She really liked it when she was on aspen but she's in quarantine right now so I wanted cleaning to be easy....
