Study Reveals Bedbugs Have Color Preferences

According to a recent study published in the Journal of Medical Entomology, bedbugs prefer the colors red and black.
The study also showed that bedbugs seem to be repelled by white, yellow and green.
During the experiment, scientists put bedbugs in Petri dishes with tiny paper tents of various colors, CNN reported.
All of the bugs ran to the tents quickly, which was expected since they spend the majority of their time living in cracks and crevices. However, when the insects were given a choice of colors, they went for the black and red tents and steered clear of the white, yellow and green tents, CNN said.
"We joked that we are all going to buy bright yellow luggage bags because the bedbugs seem not to prefer them, or not to prefer laying eggs on them," University of Florida urban entomology research scientist Roberto Pereira, who helped conduct the study, told CNN.
Pereira told CNN that bright yellow suitcases could stop bedbugs from laying eggs in them or hitching a ride home with hotel guests, but the insects could still hide in dark folds of fabric.
University of Arizona associate professor of urban entomology Dawn Gouge was not part of the study but told CNN about other ways to avoid bringing home bedbugs. Gouge suggests using suitcases with hard exteriors and insists that travelers never take suitcases into a bedroom or put them on a couch. He said the best thing travelers can do is to pack and unpack in a garage.
