She kept her pinky down, right? Are you seeing any mites anywhere? Does she seem to tolerate the soak alright? (make sure she doesn't drink it)
If no major issues, I'd keep soaking her once a day. I've not used that spray, I thought that was supposed to go on the snake? (PAM goes on substrate towels...)
I don't know how effective it is, you might not need both Nat Chem spray & soaks, especially if you're going to use PAM also??? There are no "ill effects" from the
soaks, that's the safest & most low-tech method, but as I said before, it can miss some mites...it's just the fastest way to reduce the numbers of mites, for the
safety of the snake. (It's a little stressful, sure...but so is applying the spray, & all the cage disruption...can't be helped)
