Sacramento county residents have been bombarded with aerial spraying of pyrethrins and piperonyl butoxide for the past 5 nights wihout informed consent ot sufficient notice to protect themselves. Sacramento-Yolo Mosquito Vector Control Board has stated the chemicals used are harmless when in fact they have been shown to cause cancer and other mutations. Due to certain exemptions, the Board has not had to apply for permits, gain property access or even inform the public of the actions they are taking. The aerial spraying is designed to stop the spread of West Nile Virus, and contains Pyrethrins and Piperonyl Butoxide in the form of a product called Evergreen 60-6, and is sprayed each night between 8 pm and midnight. Residents were given no fair warning and have been told to stay inside, shut off air conditioners, bring in children's toys, pets, etc during the spray, but that it is "completely harmless." These chemicals have been found to cause cancer in laboratory animals and have increased the probability of leukemia in farm workers. Organizers are planning a rally on Friday to bring attention to the issue. Read more here | Blowing the Whistle on West Nile - Shades of 1950's and DDT | No Spray's Website
