Frisco plans to spray for mosquitoes Sept. 26-27 near the Warren Sports Complex after a 15th local mosquito pool tested positive this season for West Nile virus.

A third-party contractor will fog a designated area along North County Road and Eldorado Parkway near the Warren Sports Complex on the city's northside. The treatment is slated to begin at 9 p.m. Sept. 26 and continue until 5 a.m. Sept. 27. The spraying will then repeat for the same hours that evening and into the morning of Sept. 28.

The city shared a list of precautions for West Nile virus promoted by the Texas Department of State Health Services:

• Use approved insect repellents that contain DEET, picaridin or oil of lemon eucalyptus every time you go outside.

• Drain standing water that collects in bird baths, French drains, clogged gutters, saucers under potted plants and “splash blocks” at the end of gutter down spouts.

• Wear long sleeves and pants at dawn and dusk.

• Use air conditioning and make sure doors and windows have intact screens.

No human cases of the virus have been confirmed in Frisco, though Plano officials announced Sept. 2 that a human case had been identified there.

Frisco began testing for mosquitoes May 1.

The city previously announced Sept. 11 that a mosquito pool tested positive for West Nile virus along North County Road near the Warren Sports Complex. That was part of the 11th and 12th positive pools announcement along with Hickory Street near Oakbrook Park.

Frisco confirmed the first positive test of a mosquito pool near Oakbrook Park along Hickory Street on May 29.

The Cottonwood Creek Greenbelt area was the location of the second positive test reported on June 5. Frisco then sprayed for mosquitoes in that area July 11-12, July 25-26, Aug. 1-2, Aug. 8-10 and Aug. 29-30 after the fourth through seventh and 10th mosquito pools tested positive for West Nile virus.

The third positive test was confirmed June 22, when city officials said they would be increasing surveillance efforts and treating areas near Whitefish Lake Drive and the Plantation Springs neighborhood. Plantation Springs is located south of Lebanon Road and north of the Sam Rayburn Tollway on Frisco's east side.

The Village Lakes neighborhood near Copper Point Lane was the location of the eighth positive pool confirmed by the city on Aug. 14.

The ninth positive test was reported Aug. 21 near Hickory Creek, which is near the intersection of Hickory Street and Preston Road.

Frisco announced the 13th and 14th positive pools on Sept. 18 near Panther Creek Parkway and Teel Parkway in the Grayhawk neighborhood and in the Village Lakes neighborhood between Legacy Drive and Teel Parkway.
