This from CNN.
Scientists in the U.S. are developing a laser gun that could kill millions of mosquitoes in minutes. The laser, which has been dubbed a “weapon of mosquito destruction” fires at mosquitoes once it detects the audio frequency created by the beating of its wings. The laser beam then destroys the mosquito, burning it on the spot.
It all sounds great until you realize that they’ve probably got one for humans too. Just to be safe, keep your wings still.
