Lasers are perhaps the only force of nature powerful enough to stop mosquitoes.

In a lab in this Seattle suburb, researchers in long white coats recently stood watching a small glass box of bugs. Every few seconds, a contraption 100 feet away shot a beam that hit the buzzing mosquitoes, one by one, with a spot of red light.

The insects survived this particular test, which used a non-lethal laser. But if these researchers have their way, the Cold War missile-defense strategy will be reborn as a WMD: Weapon of Mosquito Destruction. ...

The scientists envision their technology might one day be used to draw a laser barrier around a house or village that could kill or blind the bugs. Or, laser-equipped drone aircraft could track bugs by radar, sweeping the sky with death-dealing photons.

They now face one big challenge: deciding how strong to make the weapon. The laser has to be weak enough to not harm humans and smart enough to avoid hitting useful bugs. "You could kill billions of mosquitoes a night, and you could do so without harming butterflies," says Mr. Myhrvold.

Well, mosquitoes are a good start; we can worry about how to kill the butterflies later.
