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.
Looks kind of like fly pupa.
It isn't ant or termite. Doesn't look flat enough for bedbugs. Probably not a beetle.
