Air sewerage against mosquitoes
I tested this idea out by letting the air extractor from my bathroom
run all night long and slightly opening a window from my bedroom.
The curtains would ensure that the mosquitoes saw no movement
inside. All night long, no air from the inside of my bedroom did
spill out of the window, because of the negative pressure. Hence my
scent was not present in the outside anywhere close to the window. A
fan was slowly blowing inside the bedroom to further dilute any
scent that might attract a mosquito towards me.
It worked as planned. I had no bites in the morning, despite having
slept with an open window, with an extractor actively sucking in
nice fresh air from the outside. It's quite counterintuitive.
Outside air, that contains mosquitoes, was actively being sucked
inside yet no mosquito entered. They probably even did actively
avoid to be sucked in.
Had I slept inside a tent, I would have used a hose with a little
battery-run extractor to suck in the air from the most confined part
of the tent and convey it a few meters away from the tent. If don't
know if the best option is to place the output of the hose downwind
or upwind from the tent. Downwind would seem to be the safest yet
upwind would have the advantage that a mosquito that comes close to
the tent would be attracted away. (Tents do have mosquito nets but
they may be damaged and sleeping in a closed and unventilated tent
on a warm day can be very uncomfortable.)
The idea would be to equip a whole village or a medical complex with
such hoses that would carry away the scents that attract mosquitoes.
An air sewerage system. The outside electric lighting would use
wavelengths that are not visible for mosquitoes so they would less
be attracted by movement. Such an air extraction system would use
few energy to run.
The output of the system can be put to use. It can be ducted towards
a place dedicated to attract the mosquitoes, together with some
lighting effects to fake movement. Their natural predators would
gather there to feast on them, which would increase the population
of insect predators in the area.
