These days we tire of catching those filthy little creatures with old fashioned fly swatters. Besides giving our arms great exercise, and helping us relieve stress, they don’t solve the recurring problem of flies.

You can even buy those electric fly swatters these days that pulse a spark of electricity into the life of the fly.

Sometimes they work, sometimes they don’t. But it’s time to move beyond a device like a fly swatter that, let’s face it, was probably used in the middle ages.

This is where nanotechnology comes in. My fly killing invention suggestion is to develop a robot that is as small as, and looks just like, a fly. However it differs in that instead of sitting on your food or your dog’s ears, it actually does something useful: kills flies.

The device would basically be like a self-guided missile in that it would be able to track down and target flies in any area. It would be able to fly as fast, probably faster, than any fly, and when it gets to the fly it stings it like a bee.

It may sound vaguely cruel, but a robotic fly catcher would save you enormous hassles in the household. And, who knows, maybe it could be extended to catching mosquitoes too!
