While these traps don't necessarily kill bed bugs, thus they're frequently referred to as "monitors" . They are intended to serve as pro-active, early detection devices. If bed begs start showing up in the traps, it's time to call in the pest control exterminators. |
Many scientists are racing to find new ways of dealing with the bugs, including synthetic bean leaves that impale their feet and DIY traps.
Most bed bug traps and tests can cost $50 or more, but there are DIY trap is so simple and cheap that the researchers that came up with it want people to try it themselves. Ideally, it'll catch the earliest stages of an infestation, when the critters are easiest to eradicate. All you need is sugar, water, and yeast.
According to 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. Voila! You have just made a bedbug detector that beats others on the market and is much cheaper.
How This Trap Works
The yeast ferments the sugar to release carbon dioxide—the gas that bedbugs use to track down sleeping human hosts. This irresistible vapor lures insects toward the trap from long distances, and in experiments more than doubled the number that were captured. It does not kill the bugs, but it can alert homeowners to infestations at their earliest stages, when the bugs are more easily exterminated.
The trap becomes even more effective when it is baited with a cocktail consisting of nonanal and 1-octen-3-ol (two substances found in human body odor), spearmint oil, and coriander Egyptian oil. As in a previous experiment, the team found that these four chemicals are good at attracting bedbugs. Chemical 'lures', known to appeal to bed bugs, made the traps more effective. The researchers had previously found that a combination of nonanal (a chemical often used in perfumes), 1-octen-3-ol (an alcohol found in human breath and sweat), spearmint oil and coriander Egyptian oil was attractive to bed bugs. They baited one trap with this and compared it to an identical trap without bait. The baited traps were more effective both in the lab, and in an occupied apartment.
These findings are good news for those who have unwittingly brought bed bugs back from their travels. A better trap design can allow people to detect bed bugs while they are still in small numbers.Not only that, but these devices could be created at home very cheaply. Singh says "the lure is already in the process of licensing by two pest control companies…but the rest of the trap you can make at home.
