Dallas County Health and Human Services (DCHHS) has confirmed one mosquito sample testing positive for West Nile virus (WNV) in Carrollton. This sample was collected from the mosquito management area 7B. Area 7B is located between Josey Lane, Belt Line Road, Valwood Parkway, and South Broadway Street. The area can be viewed in detail at and a map can be downloaded here. The City of Carrollton conducts mosquito trapping in seven areas of the City each week of the mosquito season, May-October, and has collected 63 samples so far this year.    

Carrollton Animal Services will conduct ground-based spraying in the neighborhood outlined above, weather permitting, Tuesday, July 20 and Wednesday, July 21, beginning around 9 p.m. and continuing until completed. Spraying will not be conducted in the event of wind speeds in excess of 15 mph or inclement weather.

Cory Heiple, Environmental Services Director, encourages citizens to practice the ‘4Ds’ to reduce the risk of WNV:

  • DEET All Day, Every Day: Whenever you are outside, use insect repellants that contain DEET, picaridin, or oil of lemon eucalyptus.
  • DRESS: Wear long, loose, and light-colored clothing outside.
  • DRAIN: Remove all areas of standing water in and around your home.
  • DUSK & DAWN: Limit outdoor activities during dusk and dawn hours when mosquitoes are most active.
