Wk of July 16: Mosquito Samples Test Positive for WNV

Post Date:07/22/2020 9:26 AM

On Wednesday, July 22, Tarrant County Health Department notified the City of Colleyville of positive test results for West Nile virus in 3 of the 6 submitted mosquito samples for the week of July 16. The samples that tested positive were taken from the vicinity of Windermere, Bedford Rd, and Broadoak.  This is the 8th sample that has tested positive for WNV in 2020.

The test site will be treated with larvacide and is scheduled for continued treatment and testing. Residents within a quarter-mile of the sample area are being notified by CodeRED. This is the 2nd positive at Windermere which triggers ATV fogging at all 3 locations. The fogging is planned for Thursday (7/23) and Friday (7/24) night.

While the City is proactively working to control mosquito populations throughout town, citizen involvement, and personal protection is essential. The best defense is to practice these habits, known as the "Three Ds":

  1. Use insect repellent containing DEET, picaridin, or oil of lemon eucalyptus.
  2. Dress in long sleeves and long pants when you are outside.
  3. Drain standing water where mosquitos breed. Common breeding sites include old tires, flowerpots, and clogged rain gutters.
