City collects more positive West Nile samples to spray for mosquitoes

Dallas – Mosquito samples collected recently in four areas of Dallas have tested positive for the West Nile virus, bringing the total positive collections to 15. Samples collected at 211 N. Windomere, 600 N. Denley, 700 Brooks, and 2900 Talisman were positive for the virus. Storm sewer spraying is scheduled where appropriate and each location is being evaluated for possible spraying to reduce the number of adult mosquitoes.

City staff will also spray to reduce the overall number of mosquitoes in two Oak Cliff neighborhoods and in the Preston Hollow section of North Dallas this week. The Preston Hollow location will be sprayed on Wednesday night/Thursday morning, July 5-6. Spraying will begin after 10:30 P.M. and will conclude prior to 6:00 A.M. Spraying will be within an area bounded by Meadow Road, Hillcrest Road, Park lane and Tulane Boulevard.

In Oak Cliff, two areas will be sprayed on Thursday night/Friday morning July 6-7. Spraying will begin after 10:30 P.M., concluding before 6:00 A.M. This first area is bounded by Davis Street, west, Tyler Street, 12th Street, west, and Marlborough Avenue. The second area is bounded by 12th Street, west, Bishop Avenue, Clarendon Drive, west, Nolte Drive, and Edgefield Avenue, south. While the insecticide is considered safe, residents and visitors in the area should avoid the spray by staying indoors, or if in a vehicle by staying in the vehicle with the windows up and the air conditioner on until the spray is no longer visible. Fish ponds should also be covered.

Dallas residents are urged to take precautions against mosquito bites by reducing outdoor activity during evening and nighttime hours. Residents who are outside during these times should cover their arms and legs and use a mosquito repellant.

Prevent mosquito breeding: Residents should eliminate standing water to prevent mosquito breeding and the spread of West Nile Virus. Breeding places for mosquitoes include swimming pools that are not kept clean, stagnant ponds, pet watering dishes, birdbaths, potted plants, old tires, empty containers, toys and clogged rain gutters. Standing water should be eliminated promptly, as mosquitoes can grow from egg to adult in as little as seven days.

To report standing water or mosquito problems Dallas residents should call 3-1-1. For additional information on Mosquito Control, visit the City’s Web site at
