Man i just did a clean wipe of all those surfaces just before discovering this too.

I'm interested in hearing if anyone has had better luck with predatory mites than sprays. I really want to try but it's expensive for me to get them from here SPIDER MITE PREDATORS FACT SHEET & Release Instructions

Another thought I'm having is just chopping them down at the base and literally just trashing any mites/eggs on the leaves, hoping it's not a huge issue on my palms, and trying to prevent them from returning to new banana leaves. seems extreme though
