A mosquito trap in an Arlington neighborhood near Douglas Court and North Cooper Street tested positive for West Nile virus, prompting the city to roll out overnight spraying in the area. The timing is no coincidence, as county mosquito surveillance is ramping up for the summer season, and officials are again asking residents to do their part by draining standing water, using insect repellent, and avoiding outdoor activities at dusk and dawn.
According to the Fort Worth Report, Tarrant County Public Health identified the positive trap near Douglas Court at North Cooper Street and then alerted the City of Arlington. Tarrant County Public Health conducts weekly arbovirus surveillance across the county and posts testing updates as part of its regular mosquito season monitoring.
Where and When Spraying Will Happen
Per the City of Arlington, the city’s contractor will carry out targeted ground spraying within a half-mile radius of the positive trap on two consecutive nights. Crews will use an ultra-low-volume, water-based permethrin product and are set to operate overnight between 9 p.m. and 5 a.m., weather permitting. Signs will be posted in affected neighborhoods ahead of time so residents know when trucks are coming through. People with chemical sensitivities or breathing conditions are advised to remain indoors while spraying is underway.
How To Protect Yourself
Health officials repeat the “Three Ds” of mosquito protection: DEET, Dress, and Drain. Use EPA-registered repellents that contain DEET or picaridin, wear long sleeves and long pants when possible, and remove standing water around your home, guidance that mirrors recommendations from the Centers for Disease Control and Prevention. Mosquitoes can breed in as little as three to four days of standing water, so it pays to check birdbaths, gutters, flowerpots, and other containers regularly.
If you develop a fever, a severe headache, neck stiffness, or confusion after a mosquito bite, you should seek medical care promptly and mention the possible exposure.
What To Expect And How To Get Info
The city plans to alert neighbors about spraying through social media, posted street signs, and the Ask Arlington app. Residents can report standing water or mosquito problems through the app or by calling the Action Center at 817-459-6777. The City of Arlington also outlines how it uses larviciding and targeted ground spraying in coordination with county health officials once a positive trap is confirmed.
Where This Fits In The Bigger Picture
West Nile activity has been showing up across Texas this spring, and Harris County has reported at least one human neuroinvasive case earlier in the season. That backdrop is part of why local agencies keep dense networks of mosquito traps in place. Axios has reported on early detections in Harris County, while local programs such as Tarrant County Public Health continue to monitor traps and trigger targeted responses when positive samples appear.
If you are worried about possible exposure or symptoms, contact your health care provider and mention any recent mosquito contact. For more details on West Nile symptoms, testing, and prevention, visit the CDC.
