I filed this thread under Useless Makework Science.
Now, the discovery of the light frequency fatal to mosquitos; or locusts... there is useful science. But actual work.
Can't have that.
Folks are missing the gem: LEDs can potentially drive away mosquitoes and other insects.
Where I live that’s a big deal!
An aside: I have a grow light. It has LEDs in both the blue and red spectrum, because those are the spectrums plants use. When it shines on an object the object appears purple.
I can attest that bugs do not fear red, blue, or purple light. I think they actually like it.
