I don't know what the exact frequency is but I can tell you it's up
in the 19KHz range. I know this because it hurts my ears. My ears are
sensitive to the frequency and my friend has one in his attic (we were
working on the roof). I had severe head aches from that noise maker.
My friend forgot it was on (for a couple of years). Didn't make the
mosquitoes go away though.
