Mosquito Control Spraying for the Sioux Falls Region

If weather conditions permit, the City of Sioux Falls Health Department will be spraying for mosquitoes in targeted areas of Sioux Falls this evening.

Sioux Falls Zones 11 and 18 are scheduled for spraying this evening between 8 p.m. and 1 a.m. For the locations and boundaries of our spraying zones, please review the interactive map on the Sioux Falls Health Department webpage (

Additionally, the Health Department will continue to spray the City bike trail one to two times a week in the morning between 3 a.m. to 7 a.m. or the evening between 10 p.m. to 1 a.m.

All spraying is subject to change due to weather conditions.

This targeted spray effort is being conducted in response to increased numbers of mosquito populations. The Sioux Falls Mosquito Control Program follows a phased-response guideline created by the CDC that is used to determine when spray events and other treatments are needed.

The City will be using the product Aqua Reslin for spray treatments. Products used by the City of Sioux Falls are designed to break down in the environment quickly and are used at very low concentrations. Aqua Reslin is a product approved for use by the EPA in residential areas for adult mosquito control.

As progress is made toward completing the spraying process, updates will be placed on the City’s website.
