After a mosquito trap in the 75137 ZIP code tested positive for West Nile virus, Duncanville is rolling out overnight ground spraying today, from 9:00 p.m. to 5:00 a.m., weather permitting. City officials are urging residents in the affected neighborhoods to stay indoors during the operation and to bring pets inside until the trucks are done.
Where and When the Spraying Will Happen
The spray zone covers an area generally south of E. Wheatland Road, east of Santa Fe Trail, north of the southern city limits, and west of E. Hwy. 67. Fogging trucks will run overnight to limit how many people are out while the insecticide is in use. The schedule was posted yesterday and includes a map of the target area, according to the City of Duncanville.
County Role and Why Officials Are Spraying
Duncanville says it is moving ahead with spraying on the recommendation of Dallas County Health and Human Services. The county typically calls for ground spraying after a laboratory confirms West Nile in mosquito traps, a protocol outlined on its West Nile resource page, according to DCHHS.
What Residents Should Do
People who live inside the spray zone are asked to stay indoors with windows closed while the trucks are operating and to keep pets inside until the fog has settled. City guidance also reminds residents to dump standing water, use EPA-registered repellents that contain DEET, and cut back on outdoor time at dawn and dusk when mosquitoes are most active, according to the City of Duncanville.
Why This Is Happening Now
The move comes as mosquito season ramps up across North Texas and more traps test positive for West Nile, triggering targeted spraying in several communities. Nearby Dallas also scheduled fogging this week after its own positive traps, a pattern noted in local coverage and county updates, according to Patch.
