Four Mosquito Pools Test Positive for WNV; Frisco to Spray June 16 & 17

(July 15, 2016) The City of Frisco will spray for mosquitoes July 16 and 17 after receiving confirmation four mosquito pools tested ‘positive’ for West Nile virus (WNV). On the first evening, spraying will start at 9 p.m. Saturday and continue through 6 a.m. Sunday. Spraying will resume at 9 p.m. Sunday and continue through 6 a.m. Monday.

The city will conduct ‘ground spraying’ to target the Frisco Lakes neighborhood (see attached map). A third-party contractor will target several neighborhoods in the areas south of Warren Parkway and east of Legacy Drive (see attached map).

Ground spraying involves a ‘fogger truck’, which emits a 300 foot swath of spray from the back of the vehicle. City staff recommends residents stay indoors during spraying, bring pets indoors and refresh animals’ outdoor water dishes the next morning.   

If the ‘fogger truck’ encounters pets or people, the driver will turn off the ‘fogger’ and go around the individuals or pets.

Contractors will also use ‘backpack’ sprayers to target accessible ‘greenbelt’ areas surrounding mosquito trap sites located in the Starwood neighborhood (see attached map) as well as in the area immediately north and south of Little Ranch Road, between Teel Parkway and F.M. 423 (see attached map).

Today’s confirmations bring the number of ‘positive’ mosquito pools in Frisco this summer to eight. No human cases are confirmed here.

“According to our city-contracted entomologist, every site is unique,” said Julie Stallcup, Environmental Health Supervisor. “Our contractors tailor their response to a ‘positive’ West Nile virus trap site according to factors like population density and the size of the impacted area. In some situations, it’s more effective to conduct ground spraying. In other areas, like greenbelts, it’s best to directly target the trap site with ‘backpack’ sprayers.”

The City of Frisco supports four precautionary habits promoted by the Texas Department of State Health Services.

1. Use approved insect repellents: Use repellent every time you go outside. Approved repellents contain DEET, picaridin or oil of lemon eucalyptus. Follow label instructions.

2. Drain standing water: Drain water that collects in cans, tires, buckets, rain gutters, and saucers under potted plants. Mosquitoes breed in stagnant water.

3. Wear long sleeves, pants at dawn and dusk (when mosquitoes are most active).

4. Use air conditioning: Make sure doors and windows are screened – and those screens are intact.

In accordance with its plan, Frisco began testing for mosquitoes May 1. For more information, contact the City of Frisco’s Health & Food Safety Division of the Development Services Department at 972-292-5304 or go to www.FriscoTexas.gov.
