An area in Dallas is going to be sprayed for the West Nile Virus after samples tested positive. Here is what that means.

The City of Dallas put out a press release about the spraying on Friday. According to the press release, an area in Northwest Dallas bounded by Ruth Ann Dr., Ferguson Rd., Joaquin Dr., Barnes Bridge Rd., and Santa Teresa Ave., will be sprayed for West Nile Virus.

The spraying will take place, weather permitting, between 9 p.m. and 5 a.m. each night from Saturday, May 16 to Sunday, May 17.

While the United States Environmental Agency approves the insecticide that will be used for treatment, residents in the above areas should avoid contact with the spray by staying indoors.

People inside a vehicle while trucks are actively spraying should remain in their vehicles with the windows up and the air conditioner on until the trucks pass through and the spray is no longer visible.

People who are out during the schedule spraying time should be alert for trucks and not follow them. Residents who come into contact with the spray are advised to wash the affected area thoroughly with soap and water. The spray breaks down quickly in the presence of sunlight and has no residual effect.

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