Bed bugs have become a global epidemic. Detecting infestations early is the key to successful eradication. Scientists at Simon Fraser University have identified the bed bug aggregation pheromone. They extracted the pheromone from the bugs' feces and cast cuticle, and analyzed extracts by state-of-the-art technology including gas chromatography-mass spectrometry and nuclear magnetic resonance spectroscopy. In lab and field bioassays, they demonstrated that a 6-component pheromone blend is highly effective in attracting bed bugs to, and retaining them in, cardboard shelter traps. The pheromone technology can now be developed as a tool to help detect, and possibly control, bed bug infestations.
