This is the time of year when the mosquito districts get into high gear, and some of them spray, spray, spray.  This poses risks to humans (particularly asthmatics, children and pregnant women), kills off beneficial insects (like dragonflies which eat mosquitos, and bees, our primary pollinators, and butterflies), and is mostly ineffective at any real control.

   James Irwin of Columbia, SC has done some research, and made enough noise (mosquito spraying is more a matter of politics than science) to get a moratorium on using adulticides in some SC spray districts.  Take a look at what he's doing, perhaps you can do as much good in your area:    http://nospraynews.org
