EPA developed this fact sheet because an increasing number of households have purchased timed-release outdoor residential misting systems to control mosquitoes and other insects around the home. However, advertisers, the media, and other sources sometimes provide information about misting systems that is difficult to understand or might conflict with other information. The new Web page describes outdoor residential misting systems and discusses the pesticides used in the systems, their safety and effectiveness, and the regulatory authority of EPA and state governments regarding misting systems. The Outdoor Residential Misting Systems fact sheet is available on EPA's Web site at http://www.epa.gov/pesticides/factsheets/misting_systems.htm.
