Yes, bed bugs are attracted to the carbon dioxide humans and animals exhale and to some extent, the warmth of our bodies, rather than the smell of blood. They do, however, need blood to survive, but they do not have a preference for blood type or detect it by smell. Their method of finding a host is not based on the scent of blood, but through these other environmental cues.
