Mosquito pool tests positive for WNV; Frisco to spray Aug. 30 - 31 

(August 28, 2014) This weekend, the City of Frisco will ground spray for mosquitoes on the city’s west side after receiving confirmation a mosquito pool tested ‘positive’ for West Nile virus (WNV).  

Frisco will spray for mosquitoes two nights, August 30 and 31 (Saturday and Sunday) beginning at
10 p.m. through 6 a.m. each night, weather permitting. The area to be sprayed is bordered by the
Dallas North Tollway (DNT) to the north and east; Lebanon to the south; and railroad tracks to the west. Click here to see a map.   

A City of Frisco ‘fogger truck’ will spray the impacted neighborhoods. The truck will emit 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. The spray produces a very fine mist.  Experts report no negative impact to stationary objects.  Pool water, if properly filtrated, will not be affected.   

Today’s WNV confirmation marks the second mosquito pool to test positive in Frisco this season.
No human cases are confirmed in Frisco, to date. 

The city’s third party contractor, who is an entomologist, recommends spraying in this instance because the number of ‘target mosquitoes’ found in the area traps have increased tremendously. 

“’Target’ mosquitoes are Culex mosquitoes, which have the potential to transmit West Nile virus,” said Julie Stallcup, Environmental Health Supervisor.  “When we began trapping for mosquitoes in this area back in May, our traps were collecting fewer than a half dozen Culex mosquitoes in every sample. Today, we’re seeing high, double digit numbers.”  

Additionally, entomologists report cities throughout the region are experiencing higher numbers of target mosquitoes and more mosquito pools testing positive for the virus.

The City of Frisco supports precautionary steps promoted by the Texas Department of State Health Services – and commonly referred to as “The Four D’s”:  

-        DRAIN all standing water;

-        DRESS in light-colored, long sleeve clothing when outdoors;

-        DEET…Use mosquito repellants that contain Deet; 

-        DUSK OR DAWN…Avoid outdoor activities during these hours when mosquitoes are most active.   

“Experts say this time of year, people are at higher risk for contracting West Nile virus, which is why practicing the ‘four Ds’ is even more important,” said Stallcup.
