When tackling a bed bug problem, many people focus on extermination.
But understanding bed bug behaviour can also be key to prevention.
One lesser-known fact is that bed bugs may be influenced by colour and material types.
Do Bed Bugs Prefer Certain Colours?
Yes, research has shown that bed bugs are indeed drawn to specific colours.
A study published in the Journal of Medical Entomology found that bed bugs tend to prefer red and black over lighter colours like yellow and green.
The reason? Darker colours mimic the shadows and hiding spots they naturally seek during the day. Red may also resemble the colour of other bed bugs, signalling a safe harbour.
If you’re trying to deter bed bugs, this means opting for lighter-coloured bed linens, furniture, or luggage could potentially reduce the appeal of your environment, although that is by no means a standalone solution.
What About Materials?
Bed bugs are opportunistic and aren’t fussy eaters, but they do favour materials that offer crevices to hide in.
Coarse fabrics like wood, cardboard, and textured upholstery provide better shelter than smooth materials like plastic or metal.
They’re especially fond of seams, folds, and tufts in mattresses, sofas, and clothing.
Cluttered environments or belongings made of porous materials also make ideal hiding places, helping them avoid detection while staying close to their food source—us.
Final Thoughts
While choosing light-coloured or smooth materials might make your home marginally less appealing to bed bugs, these pests are extremely adaptable.
The most effective defence remains vigilance: regular inspections, sealing cracks, and acting quickly at the first signs of infestation.
Prevention and professional bed bug treatment remain key in keeping your home bed bug-free.
