Third positive test of 2025 prompts mosquito control measures and resident precautions.
Mosquito Pool Tests Positive For West Nile Virus
The City of Frisco confirmed on Friday, July 18, that one mosquito pool tested positive for West Nile virus (WNV). The sample was collected near River Trail and Copper Point Lane, close to several neighborhoods.
Ground spraying will began at 9 p.m. Friday and continued overnight until 5 a.m. Saturday. The same schedule took place on Saturday night, July 19, ending at 5 a.m. Sunday morning.
Spraying covered portions of Village Lakes, Crosspointe Park, Park Place Estates, Pearson Farms, Heritage Village, and Westfalls Village. This is the third positive mosquito pool identified in Frisco this season. No human cases of WNV have been reported in Frisco this year.
City Response and Spraying Plan
Frisco conducts mosquito surveillance from May through mid-November each year. Samples are collected weekly and tested for WNV by a third-party lab.
“Mosquito control is about protecting public health while keeping residents informed,”
the City of Frisco’s Health and Food Safety Division mentioned in a public notice.
Truck-mounted ground sprayers will release an ultra-low volume (ULV) mist designed to target adult mosquitoes. City officials note the insecticide is approved by the Environmental Protection Agency (EPA) and is considered safe for people, pets, and wildlife when used correctly.
Residents can view the city’s GIS Mosquito Dashboard to track positive pools and past spraying events.
What Residents Can Do
The Texas Department of State Health Services (DSHS) promotes three key steps:
Wear: Long sleeves and pants at dawn and dusk, when mosquitoes are most active.
Apply: Use EPA-approved repellents containing DEET, picaridin, or oil of lemon eucalyptus.
Remove: Eliminate standing water in bird baths, clogged gutters, potted plant saucers, and splash blocks.
“Even a bottle cap of water can become a breeding site,” DSHS notes. “Residents play a critical role in prevention by checking their yards regularly.”
Regional and Historical Context
West Nile virus has been a recurring concern in North Texas since the early 2000s. In 2012, Dallas County declared a state of emergency after hundreds of cases were reported across the region.
In the summer of 2024, Collin County confirmed 17 human cases of WNV, most contracted between July and September. While Frisco did not report any human cases in 2024, city records show several positive mosquito pools.
According to the Centers for Disease Control and Prevention (CDC), about 20 percent of people infected with WNV develop mild symptoms such as fever, headache, or body aches. Less than 1 percent experience severe neurological illness. Older adults and those with weakened immune systems face higher risk.
Why This Matters for Frisco
The presence of WNV-positive pools underscores the importance of community participation in mosquito control. As Frisco grows, more homes, landscaping, and standing water create new mosquito habitats.
The city’s testing and spraying program reduces risk, but everyday actions by residents remain essential. A clogged gutter or neglected planter can become a breeding ground that undermines broader efforts.
“Mosquito control is not just the city’s job, it is everyone’s job,” DSHS emphasizes. “Community participation is the most effective line of defense.”
Looking Ahead
Mosquito surveillance will continue in Frisco until mid-November. With Fall in full swing, additional positive tests are possible.
Through regular testing, targeted spraying, and active resident involvement, the city aims to manage risk while maintaining a safe and healthy environment for the community.
