Ask HN: Mosquito Killing / Preventing Innovations

Last night I had mosquitoes in my bedroom. While I don't like getting stung the worst thing for me is the buzzing sound they make. I can't sleep when I hear this sound. I closed the windows and doors and went hunting and after killing one I thought I was done. I wasn't. I was up dozens of times, tired and angry, hunting and killing and listening for buzzing sounds. I also sprayed myself and my bed with anti-mosquito spray but that did not help, they still came close enough so I could hear the dreaded buzzing.

I know that the open window was a mistake. I know I should have installed some form of net or something like that. I will do this soon.

However, I wondered also if there isn't anything new in the fight against mosquitoes. A new life hack, a trap or spray that actually works, a sacrificial offering to keep them occupied or preferably something like this:

A few microphones (e.g. from an ultrasound distance sensor) that can triangulate the position of the mosquito and then use this position to direct a death ray of some kind (laser, microwaves, whatever) directly at the mosquito (without killing me if the mosquito is close).
