What is happening to my BP's nose?

[Bogertophis]

Usually easy to handle but is squirmy when I try to pick her up now.
Tried with a damp towel but she wouldn't let me get close enough, will try with a wet Q-tip today after work. Thanks for the advice.

Well you're much bigger than she is (I'm assuming) so I expect you to "win" this battle... but snakes are easier to treat when you don't go directly to the task at hand.

Take a little time & be relaxed (like usual) so she doesn't feel like she's under attack. Imagine going to your doctor & when you walk in they put you in a choke-hold?
So once she knows you are familiar, you gently & more firmly restrain...but if a snake really struggles, it's a give & take so they don't get hurt. (like when snakes try to
"barrel-roll" to escape, you need to lighten up & start over) I find that snakes seem to realize that I'm helping them, even if they don't much care for what I have to do, I
don't get bit for doing it. When you treat a snake, try to imagine yourself in their place...that should help you accomplish your task. Not too pushy, but don't wimp out.
