I keep seeing these tiny black insects in my bathroom on the floor they are very small but
Very quick what could they be

Small, black, and quick (hopping in the air) usually means fleas. But why in the bathroom only? You'd see them everywhere. Is it possible they are everywhere? Do you have pets?

I think they may be silverfish not sure?
