Is this a Grain Mite in my Trapdoors Container?

[RezonantVoid]

Pretty simple thread. Ive never had grain mites before to my memory. I do have a couple of other tiny mites but they look different to this one in the pic. So far I have only seen one. If this is a grain Mite, will they affect my trapdoors? If so I'll take measures to control them but just curious. In the pic it's that white circle under the crickets leg

Could be. Are you in an environment where they are found? Finding a single grain mite is as close as it gets to mathematically impossible. Grab your magnifying glass and start your search.
