Do that ^ ^ ^ and then keep checking for mites every day or so (with as little disruption as you can manage). Letting a snake relax & settle in with NO handling
is one of the best things you can do...their immune system suffers when re-homed & handling is stressful until they learn gradually not to fear us. But mites can
quickly overwhelm a small snake especially, so don't be complacent or too trusting of any source...mites "happen" & can kill your snake faster than you might think.
No matter how nice some substrates hold humidity for species like BPs, you want your new snake on white paper towels for a substrate & don't over-do the
decor; they need hides, but all that other stuff (aka "clutter") it's best to wait on, because you'll just be throwing it out if there's mites, & it might take longer
to notice mites. Remember it's not only about getting rid of them, but hopefully before they transmit diseases to your pet.
