This program produces sound in the range of 16000Hz to 20000Hz which is beyond the audiable range of humans. Pests and other animals can though hear the very same frequency. This sound produces an undesirable effect on mosquitos and other pests thus restrains them from flying.
I can hardly imagine, how author of this tool and anyone out there could get 16KHz+ out of his speakers, but… Moreover, human ear can hear 40HZ to 20KHZ, mosquitos 18k unto 24k, PC loudspeakers can produce sound upto 17/18k.
Hence, the program will probably kill your acoustic, instead of killing the mosquito arround you.
Besides critical thinking, it was proven that these type of things are not effective.
If you still want to try, you can download this software from allmosquito web.
