COLUMBUS (WCMH) — Want to keep the bedbugs away? Then you should avoid colors like red and grey.

A new study finds bedbugs are attracted to certain colors, CNN reports. Researchers came to the conclusion after placing bedbugs in Petri dishes with different colored paper.

The bugs quickly crawled to papers that had dark colors, like black and red. They were less likely to go towards colors such as white, bright yellow and green.

The most common way people get bedbugs into their own home is when they stay at an infested hotel. The insects then hitch a ride on your dark colored suitcases.

“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,” said urban entomology research scientist Roberto Pereira.

Pereira says bedbugs probably instinctively prefer darker colored shelters over bright colors because “they offer better protection from predators such as ants and spiders” but also added that “it’s hard to know what bedbugs are ‘thinking.'”What others are clicking on:
