We are aware that bed bugs are attracted to carbon dioxide. When we fall into a deep sleep, as we exhale, we emit carbon dioxide which attracts bed bugs to come out from hiding. Bed bugs are also attracted to body heat that is generated by humans.
But here's something interesting we bet you haven't heard of before. According to an article published in Newsweek Magazine, bed bugs are also attracted to color.
The article states that bed bugs are specifically attracted to the colors black and red, and do not like the colors green, yellow, and white.
Bed bugs are not picky about cleanliness or hygiene. It simply doesn't matter how clean or dirty your home is. Their only objective is to seek out warmth, carbon dioxide, and finally, a blood meal.
There is a way to attract bed bugs to determine if you do have an infestation. This will not kill them but can be helpful to alert you of an infestation in its early stages.
Here's how to make a simple DIY bed bug trap according to this National Geographic article:
- Fill an old coffee cup with ten tablespoons (150 grams) of sugar, two tablespoons (30 grams) of yeast, and one and a half quarts (one and a half liters) of water, and put it in the middle of an upturned dog bowl.
- (When the yeast mixes with sugar, it releases carbon dioxide, which is what will attract the bed bugs.)
- Voila! You have just made a bed bug detector that beats others on the market and is much cheaper.
