A total of 33 West Nile virus-positive mosquito pools for the season have been found in Frisco after it was detected in two areas in the past week, according to the city.

The first location is in the 12,000 block of Rolater Road, west of Coit Road, a news release from the city said. The second location is near Potomac Lane in the Stonelake Estates neighborhood.

In response, the city will ground spray overnight on Oct. 1-2 in some areas of these neighborhoods: Fairfield Estates, Shepherds Hill, Plantation Estates, Parkside Estates and the Lakes of Preston Vineyards. The other spray area is in parts of Stonelake Estates and Custer Creek Farms.

If weather permits, a third-party contractor will apply treatment for two consecutive nights starting at 9 p.m. on Oct. 1 through 5 a.m. on Oct. 2. The schedule is the same overnight Oct. 2 through 5 a.m. Oct. 3.

Frisco has never had a higher rate of West Nile-positive pools, according to Director of Development Services John Lettelleir. Lettellier told Frisco City Council members on Sept. 21 that the environmental health department is working to treat standing water across the city, but urged that citizens help too.

“This has probably been the most active season that we’ve had,” Lettelleir said. “We also need the assistance of citizens to treat standing water around their homes. Because it doesn’t take much—just a bottlecap—to breed that type of mosquito that carries the West Nile virus.”

The city tracks this season’s West Nile-positive pools with an interactive online map.

No human cases of West Nile are confirmed in Frisco this year.

Frisco is recommending precautionary steps from the Texas Department of State Health Services:

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

  • Use insect repellants every trip outside. Approved repellents contain DEET, picaridin or oil of lemon eucalyptus.

  • Drain standing water that collects in birdbaths, French drains, clogged gutters, saucers under potted plants and splash blocks at the end of gutter downspouts as mosquitoes can breed in stagnant water.
