The Fly Catcher. £19.95. A bit too Rocky Horror for hereabouts, but your mileage may vary.
A non-toxic bait based at the bottom of the jaws lures the insect inside. As the insect crawls into the mouth of the trap, two sensors detect the insect causing the mouth to shut, swatting the insect dead. As the jaws open for the next victim Fly Catcher emits a loud burp, indicating satisfaction from catching a juicy bug. Nice one!!
