I’ve read that in the daytime, they hang out in the corners of rooms, and come onto your bed only in the middle of the night. Is that not right?
How did these critters evolve? Human beds are a relatively recent invention in the evolutionary timescale.

Many animals have nests or caves where bugs can stay while waiting for thier hosts to return. I guess the bugs followed us from caves to houses.
