Texas DSHS mosquito control update – Sept. 20, 2017

The Texas Department of State Health Services is providing an update on aerial mosquito spraying operations after Hurricane Harvey. DSHS is working with counties that have requested assistance with mosquito control to coordinate spraying by two state contractors and federal support through FEMA and the U.S. Air Force Reserve.

Flight operations treated about 581,000 acres over Harris, Liberty, Montgomery, Polk, San Jacinto and Wharton counties last night. Crews are planning to be uptonight spraying over portions of Austin, Harris, Liberty, Montgomery, Polk, San Jacinto and Waller counties, conditions permitting. As those areas are completed over the next one to two nights, planes will move on to Sabine, Galveston and Jasper counties and expect to conclude spraying this week.

A total of approximately 5.70 million acres has 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.
