Fort Bend County aerial mosquito spraying is scheduled for June 22 through June 24, 2026, as officials respond to extraordinary mosquito populations. The operation will target designated areas of the county, weather permitting, according to Fort Bend County Health and Human Services.
The Environmental Health Division said spraying will begin around sunset on Monday, June 22. Officials plan to use Dibrom Concentrate, a mosquito control pesticide registered with the Environmental Protection Agency.
Fort Bend County Aerial Mosquito Spraying Follows Emergency Declaration
The planned spraying follows a June 16 declaration by Fort Bend County Judge Daniel Wong. The declaration cited a local public health emergency due to extraordinary mosquito populations.
County officials said the emergency measure aims to protect public health. The goal is to reduce the risk of mosquito-borne disease transmission and other health impacts linked to high mosquito activity.
The spraying will focus on designated treatment areas across Fort Bend County. The county noted that planned treatment areas may change depending on conditions.
Residents should expect aerial spraying to begin around sunset. County officials said the schedule remains dependent on weather and operational conditions.
What Residents Should Know
Fort Bend County Health and Human Services said the mosquito control effort will use Dibrom Concentrate, listed as EPA registration number 5481-480. The pesticide is used in mosquito control programs to reduce adult mosquito populations.
Aerial mosquito spraying is often used when mosquito numbers increase quickly across large areas. It allows crews to treat broader zones more efficiently than ground spraying alone.
The county released a map showing the areas currently planned for treatment. Communities and areas shown on the release include locations in southern and central parts of Fort Bend County, including areas near Needville, Thompsons, Greatwood, Hungerford, Rosharon, Damon and Bonney.
Officials said those areas remain subject to change. Residents should follow county updates for the latest treatment information.
Mosquito Safety Tips for Families
Health officials also urged residents to take steps at home to reduce mosquito bites. Fort Bend County shared the “4 Ds” of mosquito safety.
Residents should avoid dusk and dawn, when mosquitoes are most active. People should also drain standing water around homes and yards.
Standing water can collect in buckets, plant saucers, gutters, tires, birdbaths and outdoor toys. Even small amounts can become mosquito breeding sites.
The county also recommends wearing long sleeves and long pants when possible. Residents should use insect repellent with DEET or another CDC-approved mosquito repellent.
These steps can help reduce bites before, during and after the aerial spraying period.
