The key to the device is a digitized organic compound sensor. Exactly how it works is proprietary, but basically, Goggin said, it detects two bedbug-specific pheromones at concentrations as small as 200 parts per million in the air. When the device “sniffs” those pheromones through its air intake, its flat-panel display lights up with alarms. The idea is that a hotel guest or a worried homeowner could sweep the device over bedding, furniture, clothes, shoes, wall sockets or anywhere else bedbugs might be hiding. Once the alarm goes off, they could start washing and spraying. 07/05/2011 - Bedbug News
