As aerial spraying is expected in parts of Dallas County from 10 p.m. to about 1 a.m., shares the latest West Nile virus updates across North Texas

5:12p Harris County (Houston) has used aerial mosquito spraying annually for 10 years. After Hurricane Ike in 2008, the county sprayed one million acres. - Jason Whitely, WFAA

5:10p Due to the spread of West Nile Virus and high infection rates, Grand Prairie will participate with Dallas County in an aerial assault against the mosquitoes that carry the disease. The aerial spray will cover all of Grand Prairie, including Tarrant County. The area north of I-30 may be sprayed as early as Friday night, Aug. 17, depending upon weather and coordination with other Dallas County cities. The rest of Grand Prairie will be announced as soon as dates and times are specified by Dallas County. Follow-up sprays may occur the following week at dates and times to be determined. Ground sprays in areas of positive test will continue as needed by the city. - Grand Prairie Press Release

5:00p Doctors warn people with asthma, ragweed allergy, or sensitive to chemicals to stay inside when West Nile aerial spraying begins in five hours. - Jason Whitely, WFAA

4:39p An observation: When I was reporting this story for the 10pm news Wednesday, Dallas County planned to spray 49,000 acres. By Thursday afternoon, that doubled to 106,000 acres.  People who thought they were not going to be sprayed Thursday night should take note of the change.  Instead of 635 being the north boundary â€" George Bush Turnpike now is.  And Richardson, Mesquite and Garland will be sprayed Thursday night too. Just want to make sure anyone who watched News 8 at 10 Wednesday is up to date. - Teresa Woodard, WFAA

4:20p The City of Mesquite has been notified by Dallas County the area of Mesquite located north of Highway 30 will receive aerial spraying for mosquitoes around 10 p.m. tonight, weather permitting. - City of Mesquite

4:05p Weather permitting, aerial spraying is expected to begin tonight in a northeast section of Dallas County to control mosquitoes and help prevent the spread of West Nile virus.

Responding to requests from Dallas-area cities, the Texas Department of State Health Services is directing two planes to begin flying at approximately 10 p.m. The planes will cover about 106,000 acres and will complete the day's spraying by 3 a.m. Spraying may be delayed or halted due to rain or windy conditions.

The planes will spray a triangular area bound by the Dallas North Tollway, the George Bush Turnpike and Interstate 30. The area includes Richardson, Garland and parts of Dallas and Mesquite. This priority area was established based on disease prevalence and city input and will follow a defined grid pattern for flight efficiency.

Five planes are scheduled to fly Friday night and possibly over the weekend to cover the remaining requested areas. A second round of spraying may occur early next week depending on post-spray mosquito counts. - Texas Department of State Health Services

3:56p Richardson says aerial spraying will include all areas within the city limit. The spraying in Dallas County begins at 10 p.m. and goes through 1 a.m. Friday. -

3:13p The City of Lancaster has announced an emergency Lancaster City Council meeting at 5 p.m. to discuss the local state of disaster and "imminent threat to public health and safety due to a severe outbreak of West Nile Virus." The meeting is open to the public. -

2:46p SPCA urges pet owners to take extra precaution during aerial spraying. While larger mammals such as horses and livestock are said to face little risk with the spraying, the SPCA recommended that pet owners bring their dogs and cats indoors, "keep all windows and doors tightly closed." -

2:11p The City of DeSoto reported they have opted out of aerial spraying and will continue with surface spraying. In a statement released by the city, officials said they came to the decision based on "the city's relatively high terrain, good drainage and significant tree coverage. -
