Frisco will spray for mosquitoes on the nights of July 25-26 near Cottonwood Creek Greenbelt after a fifth local mosquito pool tested positive for West Nile Virus.

A third-party contractor will spray a designated area in the Shaddock Creek Estates neighborhood, which is west of Legacy Drive and south of West Eldorado Parkway. The Cottonwood Creek Greenbelt is two miles of trails and wetlands east of Teel Parkway and north of Main Street.

The treatment is slated to begin at 9 p.m. July 25 and continue until 5 a.m. July 26. The spraying will then repeat for the same hours that evening and into the morning of July 27.

The city previously sprayed for mosquitos around the Cottonwood Creek Greenbelt area July 11-12 after a fourth mosquito pool tested positive for West Nile Virus in the city. That area was also the location of the second positive test reported on June 5.

Frisco began testing for mosquitoes May 1 and confirmed the first positive test of a mosquito pool near Oakbrook Park along Hickory Street on May 29. 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 city also shared four 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.
