What are the minute red spiders (that's what we always called them) that
inhabit the surface of sunny concrete and brick in the summer? We seem to
have literally millions of them this year, pick up a stone and you think
your hands are bleeding. Is there a way of destroying them?

Hello Neil,
They sound like Thrombidium mites. Why destroy them? They are harmless
enough. If you wish to discourage them - you do seem to have a large
population - then simply use water, as they prefer hot, dry conditions.
