The spray team, which uses a C-130 Hercules aircraft and a $2 million spray system, is scheduled to start spraying June 26 and continue throughout the week. The purpose of the spraying mission is to lower the number of irritations and infections associated with mosquito bites as well as minimize the threat of West Nile Virus. Spraying will commence at about 6 to 7 p.m. and will conclude at official sunset. In the event of inclement weather or high winds, spraying will be postponed. An environmental assessment determined the spraying is not harmful to humans, animals or crops. Also, the substances used will not affect parklands, wetlands, farmlands or wild and scenic areas.
