These colors may ward off bed bugs

Bed bugs may have favorite colors—as well as least favorite ones, BBC reports. Researchers placed the insects among tentlike habitats made of different colored paper and let them choose which to inhabit. The results, published in this week’s Journal of Medical Entomology, found that the creepy-crawlies prefer black and red, and dislike yellow and green. The researchers speculate that they prefer red because they typically live in groups and red is the color they display after gorging themselves on blood. Additionally, bed bugs are nocturnal, possibly explaining why they dislike the brightness of yellow and green, and instead prefer the darkness of black. The researchers emphasize that this color preference hasn’t been tested in any other context, but still … they probably won’t judge us for redecorating.
