Burleson residents in Zone 4 – the Oak Valley North subdivision – are slated for two nights of ground‑based mosquito spraying after local traps tested positive for West Nile virus. According to BurlesonTX.com, the city will operate ULV fogging trucks between 9 p.m. and 5 a.m. on Friday, Oct. 23, and Saturday, Oct. 24, weather permitting.
The spraying is part of the city’s 2025 mosquito‑control plan, which follows CDC, state and local health guidelines. This marks the fifth positive West Nile finding for the 2026 season, prompting targeted treatment rather than a citywide approach. The pesticide used, Aqua Perm‑X UL 30‑30, contains permethrin – a synthetic version of the natural insecticide found in chrysanthemum flowers – applied at concentrations that city officials say pose no significant health risk to adults, children or pets.
City officials stress that the amount of diluted insecticide landing on a typical quarter‑acre lot is less than one‑third of a teaspoon, with the active ingredient amounting to fewer than five‑hundredths of a teaspoon (about two to three drops). Residents are encouraged to take precautionary measures, especially those with asthma or other respiratory conditions. Recommended steps include staying indoors during spraying, keeping central air conditioners on, setting window‑unit vents to “closed” or “recirculate,” and removing outdoor toys, equipment, clothing and pets from the spray area.
After spraying, any exposed items should be washed with soap and water before reuse. Produce grown outdoors that was exposed to the spray should be thoroughly washed before cooking or eating. Anyone experiencing adverse reactions should seek medical care or call 911.
The city continues to scout for stagnant water and will apply larvicide where appropriate to kill mosquito larvae before they mature. Residents can report standing water that has persisted for more than seven days through the city’s 311 reporting system.
Burleson encourages homeowners to sign up for the city’s Emergency Alert system to receive real‑time notifications about spraying and other public‑health actions. Those who prefer not to have ground‑based spraying in their neighborhood may opt out by contacting Environmental Health Specialist Kristen Tanz at [email protected].
What’s next: The two‑night spraying operation will occur Oct. 23‑24, pending suitable weather. Residents should stay informed via the Emergency Alert system, report any lingering standing water, and follow the outlined safety precautions. For additional information, call 817‑426‑9848.
