Little Black Bugs in Bathroom Around Tub?

We have have these little black bugs that appear only on the tile around our over sized tub in the bathroom. They kind of look like a flea, but do not jump and are dead or barely moving, but keep appearing. There is a little off colored yellow larvae now and again around them too. We have no idea what they are. We thought initially they were coming from a large plant and we took that outside last spring.
