'Wear, Apply & Remove' as Mosquito Pool Tests Positive for WNV; City to Spray July 2 & 3

(July 2, 2021) A mosquito pool located near North County Road in Frisco tested ’positive’ this week for West Nile Virus (WNV). In response, the city will ground spray beginning tonight in areas of the Meadow Hill Estates and Frisco Springs neighborhoods (see map).  Remember to ‘Wear, Apply and Remove’ as a precaution against mosquito bites.  

A third-party contractor will apply treatment at 9 p.m. tonight, July 2, and continue through 5 a.m. Saturday, July 3.  Spraying resumes Saturday night at 9 p.m. and will finish at 5 a.m. on Sunday, July 4. 

The precautionary steps are promoted by the Texas Department of State Health Services (DSHS) and outlined below: 

  • WEAR: Wear long sleeves, pants outside at dawn and dusk when mosquitoes are most active.

  • APPLY: Use insect repellants every time you go outside. Approved repellents contain DEET, picaridin or oil of lemon eucalyptus.
  • REMOVE:  Drain standing water that collects in bird baths, French drains, clogged gutters, saucers under potted plants and ‘splash blocks’ (at end of gutter down spout). The mosquitoes that carry WNV can breed in stagnant water.

“These three steps are important to remember, particularly this weekend, as many residents will be spending more time outdoors in the evening to celebrate the Fourth of July,” said Julie Fernandez, Environmental Health Supervisor. “Don’t be caught off guard. Plan ahead to protect yourself and your family from mosquito bites.”

In accordance with its Mosquito Surveillance and Response Plan, Frisco began testing for mosquitoes May 1. No human cases of WNV are confirmed in Frisco this year.

For more information on the city’s plan, visit or contact the City of Frisco’s Health & Food Safety Division at 972-292-5304.
