Where are they coming from? Are they hiding somewhere in my apartment? They seem to be flightless. They are all the same size and very small, here's one on my finger for scale:
They might be some kind of cigarette/drugstore/pantry beetle, in which case they're pests that live wherever humans do rather than a local species.
