City to Spray Overnight August 6 & 7, After Two Mosquito Pools Test Positive for WNV

(August 6, 2021) This week two mosquito pools in Frisco tested ’positive’ for West Nile Virus (WNV). One location is at the intersection of Michelle and McCommas near Hillcrest Road. The other is in the 12,000 block of Rolater Rd., west of Coit Rd.

In response, the city will ground spray overnight August 6 and 7 in public areas of the Dominion at Panther Creek and Panther Creek Estates neighborhoods near Northeast Community Park (see map).  The other area includes parts of these neighborhoods: Fairfield Estates, Shepherds Hill, Plantation Estates, Parkside Estates and the Lakes of Preston Vineyards (see map).

Weather permitting, a third-party contractor will apply treatment for two consecutive nights starting at 9 o’clock tonight, August 6, through 5 a.m. Saturday, August 7. The schedule is the same overnight Saturday through 5 a.m. Sunday, August 8.

Frisco residents are urged to ‘Wear, Apply and Remove’ as a precaution against mosquito bites.  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.  This makes 23 positive mosquito pools in Frisco this season. 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.
