WTF are these?

[DannyDakota]

I am getting about 20 of these little blighters everyday in the bathroom.

They are very small maybe 0.5cm and black.

They are very easy to kill manually as they sit still on the wall for long periods.

Any idea what they are, are they dangerous and how can I get rid of them?

Regular bug spray doesn't work and the product the Mrs chucks down the toilet 3 times a week doesn't work either.

I used bleach in the area that they leave and multiply and it seems to work. I have to this, once every few month
