To fry a mosquito, you don't need an awful lot of energy. That means you don't need awfully big lenses to keep it human safe away from the focus.

That would depend on the distance you want to fry moskitos at, if you want to burn them at meters, you need a larger aperture to get a similar divergence angle as with cm.
