Hello guys,
Well, I know that you are thinking how could it possible (Or some of you know already this)? let me explain bit in theoretically, Ofcourse we know that Dragonflies are the mortal enemy for mosquitoes and in flight they generate sound frequencies (approximately) between 67 hz and 45 hz, depending on their sizes.
56 hz is a good average number in between those frequencies. Your pc sound card and speakers will work well for this purpose. There are many sound and tone generator programs available on the internet for both the mac and windows pc. Setup your computer with the sound/tone generator program running and then play the sound through your computer speakers. The speakers can be aimed directionally for complete room coverage.
The sound level on the speakers should be adjusted so it is barely audible. This arrangement can be setup in a bedroom where you would like to have the window open but are worried about mosquitoes. One speaker should be fairly close to where you are sleeping.
