Denton County Schedules Ground Spraying in Response to Two New Positive WNV Mosquito Traps

DCPH West Nile Update

Denton County Public Health (DCPH) is reporting two positive West Nile Virus (WNV) mosquito traps in unincorporated Denton County. The positive mosquito traps are located in the following unincorporated areas:

  • Northwest of Frisco including Frisco Ranch and Frisco Hills
  • North of Oak Point including Cross Oak Ranch and Prairie Oaks

DCPH will conduct truck-based ground spraying in the area near the positive WNV mosquito traps beginning Thursday, September 9, 2021.  The ground spraying schedule is as follows, weather permitting:

  • Wednesday, September 15, 2021 between the hours of 9 PM and 5 AM
  • Thursday, September 16, 2021 between the hours of 9 PM and 5 AM
  • Friday, September 17, 2021 between the hours of 9 PM and 5 AM

DCPH advises residents to take the following steps to minimize risk of contracting WNV:

  • Drain standing water in your yard and neighborhood to minimize mosquito breeding sites such as bird baths, flowerpots, and clogged rain gutters.  Consider the use of BTI briquettes, often called mosquito dunks, in standing water that cannot be eliminated. 
  • Dress in long sleeves and pants when you are outside and spray thin clothing with repellent.
  • Defend yourself by using EPA-registered repellent.  Check for ingredients like DEET, Picaridin, or Oil of Lemon Eucalyptus.

Detailed maps of the spray areas are located on the DCPH West Nile Virus website at DentonCounty.gov/WNV, along with additional information including mosquito maps, latest news, and facts about WNV.  Residents in the affected area are being informed via emergency alerts and signage.
