Those photos were taken under extreme magnification and bright light - the actual size is about the size of an uncooked grain of rice. Maybe smaller. This one was killed by freezing to preserve its form.

In the last few days I've started to see a lot of these - I can find one crawling across my desk every 5 or 10 minutes if I remember to look (Though I can't find where they're coming from at all). They don't move all that fast - they're frankly pretty easy to capture or squash.

In person I don't think they look very much like ants but in the closeup I think they kind of do. Also hoping they aren't termites.

Thanks for any help.

Edit: Here's a video of one scurrying across my desk too: https://imgur.com/a/ZC15gNZ
