At this point, that's what I'd do. Stay the course so you don't cause resistant germs. I agree that it might not be an RI, but better to be safe. Sometimes if snakes don't have adequate humidity they can also have some pieces of old dried up shed* (or debris from substrate) lodged in their nostrils too. *In case you're unaware, BPs shed the lining of the outer part of their nostrils when they shed their whole skin- those bits can get left behind & cause whistling sounds when they breathe.
And no, you can't delete a thread. It's really not a dumb question anyway. For every person that asks a question, there's a bunch more "lurking" & wondering the same things.![]()
