Infestation Of Tiny Red And Green Bugs?

Overnight there was a bug infestation of tiny red and green bugs, what are they? More than 90% are dead. We sprayed and washed and a couple pop up, even in other rooms.

One of us got cut on the foot and blood was on the carpet. We washed it and put it in the window to dry so the window was closed. Was it the blood that attracted them?
