I only took a quick skim through the video until after work, but my initial impressions are no. As far as I am aware there are thousands of species of insects that fall under the term "mosquito". Making thousands of species extinct is going to have catastrophic ecological results. I know some are pollinators and surely they must be a major food source for some animals.

I don't love them either, but we probably can't just eliminate them safely. I would say we could just move somewhere without them, but I don't think we would all fit in Iceland.
