Texas Department of State Health Services continues aerial mosquito spraying

The Texas Department of State Health Services is providing an update on aerial mosquito spraying operations after Hurricane Harvey.

Aerial mosquito control flights began at dusk Thursday, Sept. 8. Clarke, Texas’ mosquito control contractor, treated approximately 245,000 acres in parts of Aransas, Bee, Nueces, Refugio and San Patricio counties. Friday night will cover additional areas of those counties plus parts of Calhoun, Jim Wells and Kleberg counties, time and weather permitting.

Texas is also receiving additional assistance from FEMA. Flights by modified C-130 cargo planes from the U.S. Air Force Reserve’s 910th Airlift Wing are planned to begin as early as Saturday night over Chambers, Jefferson and Orange counties before moving on to other areas of the upper Texas coast on subsequent nights.

The goal is to reduce the effects mosquitoes are having on recovery efforts and the possibility of a future increase in mosquito-borne disease. During aerial spraying, a small amount of insecticide is sprayed over a large area, one to two tablespoons per acre. When applied according to label instructions by a licensed professional, it does not pose a health risk to people, pets or the environment. According to the EPA, people may prefer to stay inside and close windows and doors when spraying takes place, but it is not necessary.
