Do Bed Bugs transmit disease?
Evidence shows that, no, Bed Bugs do not transmit diseases unlike ticks, fleas, and mosquitoes. Although the Bed Bug feeding method is similar to a Mosquitoes there is no evidence and no studies that show Bed Bugs transmit any pathogens. Maybe it is because Cimex lectularius is so dependent on humans for food (blood), harborage, and reproduction that it would be counterproductive to kill off it’s primary host. That being said Bed Bugs do contain a variety of known pathogens in their bodies but for whatever reason these diseases do not get passed on to the human providing the blood meal.
