could be carpenter beetles, could be springtails, could be anything.

now lots of other people will come with solutions on how to eradicate them. and i tell you, identify the critters, and you have a high chance that they are completely harmless and you need to do nothing.

try to get pictures, maybe you need to drown one and then use a macro lens. anyway, try to identify the species. if its springtails, just leave them alone, they actually can be helpful. carpenter beetles can be a pest. it all depends.

be aware that actual reptile mites only spread from reptile to reptile, and they cannot survive without reptiles, they are the biggest threat, and they typically either hide perfectly or they are on the reptile. so spotting them anywhere before spotting them on the reptile is highly unlikely.

it all depends on identification. if its springtails, let them be. do they have a solid body? can they walk on water? are they bugs, with the typical body structure of a bug?
