Help with enclosure!

[XXMXX]

I’m very new to spiders and although this has nothing to do with tarantulas my jumping spider temporary enclosure has white fuzzy stuff in the webbing and the only thing that I could find that looked relatively close to it is mold or mites but it’s not moving and I can’t tell if it is mold or not? Do you have any idea as to what it could be? I spritz water in there once or twice a week but it is always dry and the wood that I collected has been dried out as well. Please tell me if I’m doing something wrong!

Could they be eggs?

There's something in the branch, probably one of the wood-boring beetles.

Yep. That or a mealworm.

looks like a hungry jumper

This makes sense as well seeing as there is a hike in the top of the branch. Did you bake the stick before you put it in?

Prob right. The moment I saw that pic I thought of Cottonwood.

OP, ask @schmiggle For a simplified step by step lignin test.
