More Positive West Nile Virus Samples

The City of Southlake has received notice from Tarrant County Public Health that five mosquito traps in Southlake and one trap in Colleyville, on the Southlake border, tested positive for the West Nile virus.

August is typically our most active month for mosquitoes and West Nile virus; despite the number of positive mosquito traps, these results align with the averages we typically see in August.

The positive trap locations were:

  • 900 block of Shady Oaks Dr.
  • 700 block of Ashleigh Ln.
  • 800 block of Shady Ln.
  • 300 block of Watermere Dr.
  • 400 block of West Highland St.
  • And 400 block of Forest Meadow Dr. in Colleyville.

In response to the current positive samples reported, the City will begin spraying at night within a half-mile radius of the positive test result locations. The spraying will start on Thursday night, August 18, and continue through Saturday night, weather permitting.  The City of Southlake will continue to work with residents and businesses to address any new concerns that may arise allowing the City to proactively address the virus before it spreads.

The City will also continue to set more traps throughout the year to ensure the safety of our residents and to address any concerns our citizens may have. Fire Chief Mike Starr says, “We want to encourage all residents and businesses to help control the mosquito population by eliminating standing water, which is critical with the rain in the forecast.”

Please remember these personal preparedness steps you can take to help protect yourself from the West Nile Virus while the City works to control the mosquito population through targeted spraying.

  • Drain standing water in artificial containers; this is the primary source of mosquitoes
  • Dress in long sleeves
  • Wear insect repellent containing DEET

The City of Southlake keeps a limited supply of mosquito dunks for our residents. The mosquito dunks can be picked up at Public Works Operations at 1950 E. Continental or DPS Headquarters at 600 State St. And as always, if you have any mosquito concerns, please reach out to our environmental coordinator at
