Dallas residents are on alert as mosquito samples have tested positive for the West Nile Virus, prompting the city to schedule targeted insecticide spraying. The nocturnal aerial assault on the bloodsuckers is slated from 9 p.m. to 5 a.m. this weekend, specifically from Saturday, August 10th, to Sunday, August 11th, weather permitting, according to the City of Dallas.

Affected neighborhoods include parts of the city bounded by prominent streets and landmarks within Council Districts 1, 6, and 12. These areas range from the vicinity of Deseret Trail and Platte River Way to Community Drive and Edgefield Avenue. Despite the Environmental Protection Agency's stamp of approval on the insecticide, residents living within the spray zones should minimize exposure by staying indoors during these hours.

The city stresses that although the insecticide breaks down swiftly in sunlight and does not have a residual effect, those who might come into contact with it should wash the area with soap and water. Motorists are also urged to keep windows up and AC on when in the vicinity of active spraying to avoid the pesticide mist.

With the threat of West Nile, Dallas residents are called to action to curb the mosquito threat by eliminating standing water that serves as breeding grounds. Places of concern include everything from unkempt swimming pools to birdbaths and even pet dishes. The point is to cut off mosquitoes at their pass—preventing their proliferation from egg to adult, which can happen in under a week. For those looking to do their part, the city is offering free mosquito dunks at Code Compliance Services District Offices along with advice on proper usage.
