making mosquito high frequency to repel

e14 Contributor over 13 years ago

I was hoping to get advice on how to generates high frequency sound that may repel mosquitoes.

Any ideas on this project ???

Dont let someone else's failure hold you back. Give it a shot. you may want to ry different frequencies or multiple frequencies.High, higher, or lower. Give it a try.

A number of studies have demonstrated that high frequency sounds do not repel mosquitos. This bit of folklore probably came about between the presence of bats, of which some species are prodigious eaters…

@chinino Why, in the face of evidence to the contrary, are you so convinced that some noise at some high frequency will upset mosqitos. ? Here is a link to supplement Michael Tria's post. http://www.bbc…

i will send a sch to do and change the capacitor to set right value to your frequency to block out mosquitos

We need to find the frequency that affects the insect ??? Is there a range that relates to bugs?

To get anywhere with this you will need to do some serious research:

Try this for starters:

There is a lot of research material on the web - you could do worse than read this article and replicate their experimental noise maker. They do not discuss mosquitos but they do give some information about which types of insect might be most affected.

It certainly seems that most of the device on the market are not effective but that for some species effective devices might be possible.
