The cities of Southlake and Grapevine conducted ground spraying Sunday after receiving positive results for the West Nile virus last week at mosquito traps.

Both cities initially planned to spray on Thursday, but inclement weather forced them to cancel those plans.

Southlake and Grapevine follow the recommended guidelines of spraying a half-mile radius around traps where mosquitoes show positive results.

Southlake officials say they are pleased with the impact the newly adopted West Nile Action Plan has had this summer.

Crews were able to spray the next day after the city had its first positive test trap earlier this month.

“Being able to take the plan through city council to have them sign off on that and approve that gives us a more effective way to respond,” said Kyle Taylor, Southlake’s coordinator and assistant to the director of Emergency Management. “It eliminates confusion. Everybody knows what’s expected of us based on the conditions.”

Prior to the plan, which was adopted in May, city staff had to get City Council to approve contracting ground spraying crews. Now that the city has a plan in place it can react more effectively. The city has an agreement with Tarrant County Public Health for testing and ground spraying.

Last week, three of the city’s five static traps turned in positive results. The pools were at 870 Shady Lane, 3240 Woodland Dr. and 700 Greymoor Place. The city also has one trap that it moves around weekly. The city sends results to Tarrant County on Tuesdays and gets results the following Wednesday. Part of the plan calls for a 24-hour notice so the city normally plans spraying on Thursdays.

The city’s first positive result came on Sept. 10 at 700 Greymoor Place. Last year, the city saw its first positive pool in late June.

Taylor said the action plan uses recommendations from both Tarrant and Denton County public health departments, Texas Department of State Health Services and the Centers for Disease Control and Prevention.

“We used the best science out there to decide how we’re going to handle this,” he said.

The plan also tackles preventative measures like educating the community and providing larvicide. It also introduced a tiered response system where each tier has clear definitions and actions.

While the West Nile season is coming to an end, the city urges residents to be vigilant.

“We are urging people to take this personally,” said Bob Price, Public Works director. “Residents should continually check their property for standing water and treat any standing water with larvicide.”

Residents are also encouraged to continue practicing the four D’s: draining standing water, dressing in long sleeves and pants, staying indoors during dawn and dusk and using insect repellant with DEET.


In Grapevine, a positive sample was detected last week in the 3500 block of Trumarc Drive. Spraying was conducted Sunday within a half-mile radius of that site.

Grapevine follows Tarrant County’s recommendations for ground spraying when West Nile virus samples test positive.

The county’s first positive sample for West Nile was reported June 27 in Grapevine, about three weeks later than last year.
