Inventors use wasps as bedbug detectors and more.

The Wasp Hound is the invention of two Georgia scientists, Glen C. Rains and W. Joe Lewis. The hand-held device contains five stinger-free, flying, parasitic wasps that can do a better job than dogs in detecting cadavers, explosives, drugs and even bedbugs. The wasps are bred to respond to different scents and can be taught to react to the whiff of bedbugs’ pheromones. Mr. Rains and Mr. Lewis are now seeking to raise $200,000 to take their invention to the next level. Here's the full story from Amy Wallace at NYTimes.
