A research group from the University of Florida conducted an experiment with bed bugs. The bugs were put in a Petri dish and the aim was to discover what color they preferred. The results showed that they reacted to red and black color the most, whereas they avoided green and yellow.
According to the scientists, this is probably because red is the same color as the color of their exterior shell and they think that it’s a big group of other bed bugs. Even though further research is still needed, the best option is to change the color of your sheets to either green or yellow and reduce the amount of bed bugs in your bedroom.
