Bedbugs are Attracted to and Repelled by Certain Colors | Scientists Discover

The parasites dislike yellow and green the most

Scientists have discovered that Bedbugs show a distinct preference for hiding in certain colors.

Bedbugs are insects and parasites that feed on human blood, more frequently chose to hide in red or black areas – suggesting these might be colors to avoid when purchasing a bed or sofa.

In the University of Florida and Union College in Lincoln, Researchers placed bedbugs in Petri dishes with different colored cards.

The insects are supposed to prefer red because it is the same color as they are and may represent a group of bedbugs and therefore safe for them. And black because it is dark and the creatures tend to live in cracks and crevices.

Their least favorite colors, suspected till today, are green and yellow.

Dr. Corraine McNeill was one of the co-authors of the study. He said it was likely the yellow colors were associated with light and disliked by bedbugs.  But green colors were not a sure means of repelling Cimex lecturalius or Bedbugs.

He believes using colors to monitor and prevent bed bugs would have to be specifically applied to some sort of trap, and it would have to be used along with another strategy for control.

The scientists believe this new knowledge might help attempts to trap the insects once established in a mattress. They also mention, Pheromones and carbon dioxide could be used in conjunction with particular colors, according to the study published in the Journal of Medical Entomology.
