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. This do-it-yourself (DIY) device to trap bedbugs was created by Narinderpal Singh, Changlu Wang, and Richard Cooper from Rutgers University in New Jersey. It does not kill the bugs, but it can alert homeowners to infestations at their earliest stages, when the bugs are more easily exterminated. "This is about early detection. When you detect the bugs, then you can call the professionals," says Singh, whose study was published in the Journal of Economic Entomology.
