I think she'll enjoy the decor, it's just a matter of mites not having places to hide if you're unlucky enough to have some arrive with the snake. Hopefully not!
If it's not too hard to install, you might take it out for now & just wait about a week+ to see if you see any issues on the substrate, then re-install it? It's really
up to you...and she may be too shy to use it at first anyway. New homes are scary, & being shipped is scary too, so new snakes need some quiet time to hide
when they first arrive anyway.
