Wood mites

[pretends2bnormal]

Your substrate has to be where they're coming from & rather than risk my snakes (from the side effects of PAM) I'd bake the substrate to kill them off
before using it. Or just toss it outside in the garden & buy something else to use. If you're determined to use the same substrate, you might have more
luck from a different supplier? I would never ever use PAM (or any other pesticide) just to eradicate harmless wood mites...

Agreed, there are far too many exposure horror stories of neurological damage to snakes to be worthwhile to use PAM for harmless things like these. I took OPs post to mean they had already used it, so didn't think to emphasize that part.

Baking is far more effective without the risk of chemicals harming the snake.
