From my admittedly weak description. Found it in my house.
It’s about the size of the head of a pin. Oval boy shape. Black with white or grey stripes. I kind of crushed it in the killing process so I don’t have a picture or a good description of legs.
Curious myself. Not matching any of the links. Mine were medium brown with white or off-white body marks. They were around for a few days, and now gone.
When I saw “head of a pin” in the OP I immediately thought “carpet beetles.” I frequently see them or their icky-looking bristly brown larvae in my home.
