Versions of this I've seen prototyped had a laser between two mirror strips so it zigzagged back and forth left and right as it went from about 10' up to the ground. The span between the mirrors was about 50'. It had a low-power always-on laser and the detector would correlate the signal with the frequency of a mosquito buzz. So if there was a mosquito anywhere on the laser path it would detect that, and then turn of a powerful laser pulse on the same path that would fry the mosquito. By putting a few of these in a line, a mosquito wall was made and it significantly reduced the mosquito population. This was in Ghana where they don't actually have that many mosquitos - nothing like northern Ontario, just the occasional one. But they carry malaria there so it is very beneficial to kill them.
