Don’t want to let the bedbugs bite? You’d better avoid red or black bedding.

Turns out the tiny bloodsuckers prefer those colors when hiding in cracks and crevices — or their “harborage,” in scientific lingo.

Researchers at the University of Florida and Union College made small harborages using colored paper in petri dishes, where the bedbugs had 10 minutes to choose the ones they liked best.

The critters favored the red and black hiding spots and avoided the green and yellow ones, according to the study published in the Journal of Medical Entomology.

The scientists speculated that the bugs avoid the lighter colors because they resemble brightly lit areas.

“I always joke with people, ‘Make sure you get yellow sheets!'” study co-author Corraine McNeill said, the Washington Post reported. “But to be very honest, I think that would be stretching the results a little too much.

“I think using colors to monitor and prevent bedbugs would have to be specifically applied to some sort of trap, and it would have to be used along with another strategy for control,” he said in a statement.

The insects are believed to prefer red because it is the same color as they are — and black simply because it is dark, like their hiding spots.

“We originally thought the bedbugs might prefer red because blood is red and that’s what they feed on,” McNeill said. “However, after doing the study, the main reason we think they preferred red colors is because bedbugs themselves appear red, so they go to these harborages because they want to be with other bedbugs, as they are known to exist in aggregations.”

The creepy-crawlers — which caused an epidemic in Manhattan a couple of years ago — keep exterminators scurrying to wipe them out with pheromone traps, carbon dioxide, vacuums and other means.
