'Wear, Apply & Remove' as Mosquito Pool Tests Positive for WNV; City to Spray June 26 & 27

(June 25, 2021) A mosquito pool in Frisco tested ’positive’ this week for West Nile Virus (WNV). In response, the city will ground spray in an area near Copper Point Ln in the Village Lakes neighborhood (see PDF of map). Remember to ‘Wear, Apply and Remove’ as a precaution against mosquito bites.  

A third-party contractor will apply treatment at 9 p.m. Saturday, June 26, and continue through 5 a.m. Sunday, June 27.  Spraying resumes Sunday night at 9 p.m. and will finish at 5 a.m. on Monday, June 28. 

“With the Fourth of July holiday coming up, and as people spend more time outdoors, we remind everyone to be proactive and follow the ‘wear, apply and remove’ guidelines,” said Julie Fernandez, Environmental Health Supervisor. “It only takes one bite from an infected mosquito to spread the disease, so protect yourself and your family and follow these three simple steps as you celebrate.”

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.

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.
