Worthington residents in several north-side neighborhoods will wake up to the hum of spray trucks early Tuesday as Columbus Public Health launches a pre-dawn mosquito fogging operation, after city traps tested positive for West Nile virus. The goal is to knock down unusually high mosquito counts and tamp down disease risk, city officials said, while neighbors are urged to take standard precautions.

Where crews will spray and why

According to the City of Worthington, Columbus Public Health will spray portions of the city between 4 and 7 a.m. on Tuesday. Targeted spray zones include Bluff View, Worthington Place, North High Acres, Worthington Estates, and Worthington Estates East.

Columbus Public Health's Vector Control program says it selects areas for adulticiding based on trap counts and positive test results, and typically treats neighborhoods in the pre-dawn hours to limit exposure. Residents who prefer their property not to be treated can submit a no-spray request or report concerns through local health services contacts, the City of Worthington notes.

Weather fueled an early season

Weather is a key driver of West Nile activity. Higher temperatures speed up mosquito development and can boost virus transmission, the CDC notes. Regional climate data show above-normal spring temperatures and pockets of heavier precipitation across the Midwest this year, which helps explain why trap counts climbed so quickly, the Midwestern Regional Climate Center reports.

How to protect yourself and what to expect

Health officials recommend a few simple moves to cut your risk. Dump standing water in yards and gutters, use EPA-registered repellents, and wear long sleeves and pants at dawn and dusk when mosquitoes are most active. During spraying, bring pets, toys, and laundry indoors.

Fogging programs typically advise residents to stay inside with windows closed for about 30 minutes after trucks pass. Neighbors can also sign up for spray notifications or submit a Do Not Spray request. The Franklin County Mosquito Management site and Columbus Public Health both publish neighborhood spray maps, schedules, and opt-out information, according to Franklin County Public Health.

A positive mosquito pool is an early warning signal rather than a sign that human cases are imminent. Still, it does trigger stepped-up trapping and public outreach while officials monitor for illness. For more information or to report standing water and mosquito concerns, residents can contact Columbus Vector Control or local health services, according to the City of Worthington.
