Enviro pesticide hysteria causes harm and is expensive.
A new study in JAMA reports:
Although ultralow-volume aerial spraying has proven effective in quickly curtailing widespread outbreaks of mosquito-borne infections, its use during this outbreak generated publicity over possible safety concerns. The ultralow-volume technique effectively kills infected adult mosquitoes with extremely low human exposure levels (<30 mL per acre) of minimally toxic pyrethroid insecticides approved by the Environmental Protection Agency for this purpose. Our time-series analyses of the daily incidence of hospital emergency department visits for skin rashes and acute respiratory distress over a 2-month period demonstrated the absence of any detectable increase in these conditions related to the 8-day period of aerial spraying, confirming similar conclusions of safety from prior research. Although the cost of 2 applications of aerial spraying over 875 062 acres in Dallas County was $1,636,348, the direct and indirect costs of the large number of human West Nile virus infections during this outbreak were estimated to exceed $8 million.
