Bed bugs appear to have a strong preference for particular colours!
According to the work in the Journal of Medical Entomology, the blood-sucking insects love black and red but hate yellow and green.
This information could help make better traps to lure and catch the bugs.
But it is too soon to say if yellow sheets can stop them living in your bed.
Bed bugs are tiny and they like to live in the seam of your mattress. They like to live close to their next meal – your blood.
Scientists carried out a series of experiments in their lab, placing bed bugs in dishes with different colour shelters made out of card.
Rather than taking cover at random, the bugs appeared to select the shelters according to their colour, showing a preference for black and red.
