New York City Department of Health is Spraying Pesticides on Streets to Prevent West Nile Virus, Warns Residents to Stay Inside ...
      The New York City Department of Health has begun spraying New York City Streets with pesticides to prevent the spread of the West Nile Virus, transmitted by mosquitos.
I once spilled a drop of chainsaw gas when refilling out in the woods. It fell in a big puddle that had thousands of mosquitoes sitting on the water. You could see the surface tension breaking like a shockwave going across the puddle and all the mosquitoes dropped right through to drown.
