Saw these while looking at apartments but have no idea what they are. they were found mostly on carpet, but some were in other parts of the unit.
edit: after looking up the suggestion of carpet beetle I am fairly convinced that it is indeed what they are. I also saw a few adult beetles that look like one of the species found in photos online. thanks everyone.
it was some rental middle man agency and she apologized claiming to have no idea what went wrong there. she said there was record of a cleaning crew showing up but no further details that would normally be on file. cleaning crew probably noped out of there, I know I would have.
