Bed Bugs are Attracted to Specific Colors

Researchers from the University of Florida and Union College in Lincoln, NE wondered whether bed bugs preferred certain colors for their hiding places, so they did some testing in the lab.
The results, which are published in the Journal of Medical Entomology, showed that the bed bugs strongly preferred red and black, and they seemed to avoid colors like green and yellow.
During the study, researchers originally thought the bed bugs might prefer red because blood is red and that’s what they feed on. However, after doing the study, the main reason they think they preferred red colors is because bed bugs themselves appear red, so they go to these harborages because they want to be with other bed bugs, as they are known to exist in aggregations.
