@Robert Gentel,
Several years ago,
in the summer, a friend of mine
used an electric device to electrocute them; filament glowed blue.
Apparently mosquitos r phototropic.
I 'd hear a zap every time one of them got it; pleasing sound.
My friend lost his n does not know how to replace it
nor how to identify it, but that was really good.
This was
for home defense.
He defended his back porch.
