Does using sound as a mosquito repellent really work or is it just garbage?

Question

There are audio clips which claim to repel them, but is there any evidence to back it?

Answer 1

None at all.  

Some of these devices claim that they repel mosquitoes by simulating the sound of a male mosquito.  I'm not sure why they think that would even work in theory - maybe they're just cynical and jaded bachelors or something.

Others claim to emulate the ultrasonic pitch of a dragonfly's wings, presuming that mosquitoes would naturally avoid one of their chief predators.  The problem being, however, that dragonflies don't produce ultrasonic sound with their wings.  Their large wings simply don't flap fast enough to create that high pitched whine we associate with little neopterous flies (like mosquitoes).

Add in to that the fact that mosquitoes are pretty much totally stone-cold deaf, and it's hard to see how the devices would even work in theory.

From anecdotal evidence, I've tried out several of them, and they have no discernible effect whatsoever.

Answer 2

It's absolute garbage, all the evidence conclusively shows that it doesn't work.
