The City of Frisco received confirmation two mosquito pools tested ‘positive’ this week for West Nile virus (WNV). The first location is along Midnight Moon Dr. in the Lone Star Ranch neighborhood. The second location is near the intersection of McCommas Dr. at Michelle Dr. in the Creekside at Preston neighborhood. 

In response, the city’s third-party contractor will ground spray overnight, August 24 and 25, starting at 9 p.m. Saturday night through 5 a.m. Sunday morning. The overnight schedule is the same on Sunday night ending at 5 a.m. Monday morning. Weather permitting, spraying will happen in some areas of these neighborhoods:

- Lone Star Ranch and Phillips Creek Ranch - see map (PDF).

- Creekside at Preston, Panther Creek Estates and Dominion at Panther Creek -see map (PDF). 

This makes four positive mosquito pools in Frisco this season. Our GIS Mosquito Dashboard shows the locations. No human cases of WNV are confirmed in Frisco this year.

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 tests for mosquito pools from May 1 through November 15.
