What can residents do to reduce exposure?
Please note, neither the USEPA nor the CDC requires relocating or taking special precautions during spraying. However, any possible exposure risk can be reduced by following some sensible actions: (1) Pay attention to notices about mosquito spraying found through newspapers, websites, automated telephone messages or notices distributed by municipal, county or state agencies. (2) Stay indoors during spraying with doors/windows closed and with air conditioners turned off to outside air. The EPA recommends that people remain indoors for at least one-hour after mosquito spraying to allow the spray to settle and dissipate. (3) Plan your activities to limit time spent outside during spray operations. Cover outside items like furniture and grills before the spraying takes place. Bring pets and items like pet food dishes and children’s toys indoors. Rinse any uncovered items left outside during spraying. (4) Consult your doctor or local Poison Control Center at 1-800-222-1222, if you think you have a reaction to the insecticide spray.
