The experiment on bed bugs was made from experts from the University of Florida. This is really smart thing to do because this is a common problem today.
They wanted to see what color these bugs prefer and that is why they putted them in a petri dish.
And the results can be seen from this picture.
As you can see the favorite colors of these bugs are the black and red and they hate yellow and green.
The question is – Why do these bugs mostly prefer the red color? The answer is quite simple. As we can see from the first image these bugs have shell that is red and because of that they think that is some group of their ‘family’ and that is why they go for red.
Will you change your sheets is only up to you, but there are many people that will do that after these facts. More studies should be done to examine these bugs and that is why this is only your choice.
