Electronic Fly Catcher

The fly catcher is an electronic fly-swatting device based on the idea of the Venus fly trap. [..] Each unit comes with a packet of non-toxic bait (more can be purchased as required) which is hidden inside the mouth of the trap. The bait attracts the fly, which crosses two sensors as it walks down the surface of the jaws. These sensors activate the jaws which then snap shut, killing the fly humanely. Once swatted the mouth re-opens with a burp, indicating it is ready for the next fly.
