I don't think this is what you're talking about but one of the ways of killing mosquitos is to lace a gallon of water with a chemical that attracts adults and kills them along with any eggs. In practice, this would basically target only females. After a quick search I found this link leading to a page of Intellectual Venture's http://www.intellectualventures.com/inventions-patents/our-inventions/photonic-fence/ http://www.intellectualventures.com/inventions-patents/our-i... It's pretty cool but unfortunately looks tied to IV. My first guess might be to avoid any criticism that by killing ALL mosquitos, they're harming the ecosystem. I guess that's wishful thinking for a company that I kind of despise even being on their website.
