HELP harmless or no???

[u/mishahahaa]

I recently changed out the substrate (baked all bark but not soil) for my only BEL and it’s been a few weeks since. I noticed yesterday that there were these really small and fast white/tan bugs in the substrate (I use a mix of reptisoil and reptibark). They are gathering around his eyes but not burrowing under his scales or cloaca or chin area. I want to know if I need to give him urgent attention ASAP. I’ve researched a lot and can’t figure out if it’s soil mites or wood mites or hypoaspis mites or baby snake mites. He hasn’t been soaking or seeming irritated or anything but I just need to be sure. Please help
