Four planes will take to the air over Dallas County Friday night to disperse mosquito-killing chemicals during the biggest outbreak of West Nile Virus in years.
Spraying will start about 9 p.m. and will cover the cities in the northwest sector of Dallas County, cities not sprayed Thursday in northeast Dallas County and the city of Dallas below Interstate 30.
Thursday night's spray area was only half covered when rain moved through around midnight, forcing the two planes in the air to land. Only about 52,000 acres of the 100,000 acres were covered, according to Dallas and Clarke chemical officials.
Late Friday morning, Dallas City Hall released a map showing the GPS track of the planes' routes Thursday night. (CLICK HERE TO SEE A ZOOMABLE PDF MAP).
Entomologists are putting out traps in last night's spray zone to see how successful the Duet chemical was. At least one FOX 4 viewer reported several dead mosquitos had fallen on her white vehicle in the Lake Highlands area.
More rain is forecast for this evening and for this weekend, especially as a strong cold front moves through on Saturday.
If weather interrupts the spray process again Friday, the planes will spray on Saturday.
But if the weather cooperates and the four planes are able to finish their planned routes, the city will not conduct aerial spraying on Saturday and Sunday, but start again on Monday.
Cities in the southern part of Dallas County have until 2 p.m. Tuesday to decide if they want to be included in the spray zone.
