Frisco announced June 5 that a second mosquito pool in the city had tested positive for West Nile Virus.

In a news release announcing the positive test, city officials said they would be increasing surveillance efforts and treating areas near Cottonwood Creek Greenbelt with larvicide as needed. The park is located east of Teel Parkway and north of Main Street.

“As people start to spend more time outdoors, we want to remind everyone about the importance of protecting ourselves and our families." Environmental Health Supervisor Julie Fernandez said in the news release.

Frisco began testing for mosquitoes May 1. The city confirmed the first positive test for West Nile Virus in a mosquito pool near Oakbrook Park along Hickory Street on May 29. Officials said no human cases of the virus have been confirmed in Frisco.

The city shared four precautions for West Nile Virus promoted by the Texas Department of State Health Services:

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

• 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.
