Just because something is “natural” doesn’t make it safe or good.
It doesn’t kill the larvae, it just gets them high so they don’t want to grow up.
I grow hemp nettle in my garden and never have mosquitos.
The real question, which is not addressed in the article (presumably because it was not studied) is how specific it is to mosquito larvae. If it is just as effective at killing other invertebrates it won’t be particularly useful outside of treatments for fountains or whatever, since you don’t want to wreck the entire insect population in a wetland just to reduce mosquito numbers.
