Denton County reports a West Nile Positive Mosquito Pool and a fourth human case of West Nile Virus


August 3, 2016 – Denton County Public Health (DCPH) is reporting a positive West Nile Virus (WNV) mosquito pool. The pool is located north east of the City of Denton. In addition, there is a fourth human case of WNV for 2016 in Denton County. The resident resides east of Argyle in the Lantana subdivision and was diagnosed with West Nile Fever.


DCPH will conduct ground spraying in the area located around the positive WNV mosquito pool for three consecutive nights, beginning Thursday, August 4-6th, 2016. The ground spraying schedule is as follows, weather permitting:


  • Thursday, August 4 between the hours of 9pm and 5am
  • Friday, August 5 between the hours of 9pm and 5am
  • Saturday, August 6 between the hours of 9pm and 5am


A detailed map of the spray area can be found at dentoncounty.com/WNVnews. Residents in the affected area are being informed.


Chief Epidemiologist Juan Rodriguez stresses that residents can play a large role in reducing their risk. “It is important for residents to drain standing water around their homes, take precautions to prevent mosquito bites while outdoors, dress appropriately and use DEET or other EPA-approved repellents,” he states.


Residents should take the following steps to reduce their risk of getting WNV:


  • Drain standing water around their homes to reduce mosquito breeding grounds. Consider use of BTI briquettes (or mosquito dunks) in water that cannot be drained, such as small ponds and drinking troughs.
  • Be aware of mosquitoes during times that they are active, Dawn, Daytime, Dusk and evening hours.
  • Apply an insect repellent that contains DEET (N,N-diethyl-m-toluamide) to exposed skin and to clothing when outdoors. The Centers for Disease Control and Prevention (CDC) also recommends Picaridin (KBR 3023).
  • Dress in pants and long sleeves when outside and/or wear permethrin-treated clothing.
