Texas DSHS mosquito control update – Sept. 12, 2017

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

In the Coastal Bend area, mosquito control flights last night by Clarke, Texas’ environmental services contractor, treated approximately 237,000 acres in Jackson and DeWitt counties. Tonight is a scheduled safety rest day for the flight crews.

Along the upper Texas coast, Texas is receiving support from the U.S. Air Force Reserve’s 910th Airlift Wing flying modified C-130 cargo planes staged out of Kelly Air Force Base in San Antonio. Last night, they treated approximately 194,000 acres over Jefferson, Orange and Chambers counties, completing Orange County. They plan to complete operations for Jefferson and Chambers counties tonight while beginning flights over Brazoria County.

A total of approximately 1.85 million acres have been sprayed across all areas. Flight schedules are subject to change.

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.

DSHS will be providing daily updates on our News Updates page.
