Doesn't seem to bother my moisture loving spiders when I dry them out, except for my big genic. She's part frog though..I think it has to do with the house we just moved into. My room gets warmer than I'm used too and being in Florida after the hurricane last month didn't help, it was several days without electricity and our windows open. The room was pretty humid... I guess it's a good thing, I'll clean all tanks out fully and cooler weather is coming, hopefully. And I'll be prepared if it happens again.Everyone gets mites occasionally . They only become a problem when they infest and there's hundreds of them.
The three week dry out works for me, you just have to make sure they're fed, and you remove any prey remains. Although a juvie or adult could easily go three weeks without food or water..hell, even a healthy sling could. Mites are something I deal with alot. I have several moist species, and drying them out occasionally has become a regular practice for me.
Humid environments will always attract mites, but they're easily dealt with
