Scientists have taken an Ikea dog bowl, leather dye, surgical tape, yeast and sugar and built a better bed bug trap. Changlu Wang, a Rutgers University entomologist, started to battle Cimex lectularius in 2006, and has a patent pending on a type of lure that is among a handful now in commercial and consumer use. But Wang and his colleagues wanted to solve several shortcomings of the devices — among them, the price and effectiveness. "It was very cheap, actually," Wang said of the resulting contraption. "It probably will cost less than $1. You can make it yourself."
