Underside of Immature Bed Bug
Bed bugs are a problem in need of a better solution. There is much interest in bed bug traps that intercept bed bugs traveling to and from a feeding site and a harborage. A group of scientists* asked, “How do bed bugs use their vision?”
Bed bugs respond to a variety of odor cues but also respond to color. They orient to black or red objects in preference to white or other colored objects. (The bed bug visual system does not distinguish black and red.) Bed bugs prefer vertical objects to horizontal ones. This information is potentially useful to those trying to design a better bed bug trap.
