One Mosquito Pool Tests 'Positive' for WNV; Frisco to Treat Friday; Saturday & Sunday Nights

(September 22, 2017) The City of Frisco will treat for mosquitoes after receiving confirmation one mosquito pool tested ‘positive’ for West Nile virus (WNV). The Cottonwood Creek Park area is scheduled for various treatments beginning Friday through Sunday.    

Beginning Friday, September 22, city staff will use larvicide to target remote areas of Cottonwood Creek Park.

Beginning Saturday, September 23, a third party contractor will use a utility task vehicle (UTV) to target off-road locations on city-owned property at Cottonwood Creek Park (click to view map).

Spraying will continue on Sunday, September 24, continuing through 6 a.m. Monday, September 25.

This ‘positive’ pool confirmation brings the total to 17 in Frisco this year. Collin County and Denton County health officials have each confirmed one human WNV case in Frisco this season.

The City of Frisco supports four precautionary habits promoted by the Texas Department of State Health Services.

  • Use approved insect repellents: Use repellent every time you go outside. Approved repellents contain DEET, picaridin or oil of lemon eucalyptus. Follow label instructions.
  • Drain standing water: Drain 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 breed in stagnant water.
  • Wear long sleeves, pants at dawn and dusk (when mosquitoes are most active).
  • Use air conditioning: Make sure doors and windows are screened – and those screens are intact.

In accordance with its plan, Frisco began testing for mosquitoes May 1.
