UPDATE: Aerial spraying for remainder of Dallas begins at 9 p.m. Friday

UPDATE, 3:30 p.m.: Dallas City Councilwoman Angela Hunt forwarded a note from city staff saying crews will spray the entire city of Dallas on Friday night and Saturday morning, with the exception of the area that was sprayed Thursday night. Spraying will begin at 9 p.m. Friday. If everything goes as planned, Friday night’s spraying will complete the first application for the city of Dallas. However, two applications will be required. The second application will be conducted two days after the first spraying to kill mosquitoes missed on the first spray as well as those that hatch within two days. The Dallas Morning News is reporting that Friday night’s application will also include Coppell, Addison, Carollton, Richardson, Farmers Branch, Garland, Mesquite (north of IH-30) and Grand Prairie.

ORIGINAL POST:

The Dallas Morning News is reporting that crews will spray the entire city of Dallas on Friday night and Saturday morning, with the exception of the area that’s already been sprayed. Crews will also spray Carollton, Addison, Richardson, Farmers Branch, Garland, part of Mesquite and Grand Prairie.

The city of Dallas just posted the above map showing, in pink, the area two planes were able to spray with the Duet pesticide Thursday night in an effort to kill mosquitoes carrying the West Nile Virus. According to the city, a rain system moved into the area at midnight, prompting them to halt spraying, which had been scheduled to continue until 3 a.m.  They watched the radar until 2 a.m., at which point the remainder of the mission was postponed. A total of 52,352 acres were sprayed, or a little over half the 100,845-acre target area for Thursday night. The city says four planes will be ready to spray Friday night. They presumably will attempt to finish the target area from last night, meaning they’ll be spraying in Far East Dallas, Mesquite and Garland. However, it’s unclear whether they’ll attempt to spray additional areas. Tonight’s forecast calls for a 30 percent chance of rain, mainly after 1 a.m. As we’ve noted, the spraying could be especially dangerous for people with compromised immune systems, including those with HIV/AIDS. Here again is that list of precautions recommended by the city:

• Minimize exposure. Avoid being outside, close windows and keep pets inside.

• If skin or clothes are exposed, wash them with soap and water.

• Rinse homegrown fruits and vegetables with water as a general precautionary measure.

• Cover small ornamental fish ponds.

• Because the chemical breaks down quickly in sunlight and water, no special precautions are suggested for outdoor swimming areas.

Aerial spraying begins tonight, includes most of Oak Lawn and Uptown

Updated map, 4:50 p.m.

Aerial spraying for mosquitoes carrying the West Nile Virus begins tonight from 10 p.m. until 1 a.m. The area of Dallas, Highland Park and University Park to be sprayed are bound by LBJ Freeway, the North Dallas Tollway and I-30.

Uptown and most of Oak Lawn are included in the spraying area. The only area bounded by those highways that is not included is Mesquite.

Another 20,000 acres may be added later today, according to a mid-morning release from the city of Dallas.

In Oak Lawn, there have been three human cases of West Nile Virus in the 75219 zip code and one case in 75235. In Uptown’s 74204 zip code, one human case has been reported. The 75235 zip code west of the Tollway is not included in tonight’s announced spraying area.

One case has been reported in each of North Oak Cliff’s two zip codes — 75208 and 75211 — but Oak Cliff, south of I-30, is not included in the spraying area.

Aerial mosquito spraying could pose risks to people with HIV/AIDS

People with HIV/AIDS are at greater risk of developing severe complications from West Nile Virus, which has led to 10 deaths in Dallas County this summer. But people with HIV/AIDS could also face greater risk from exposure to the chemicals used in aerial spraying to combat the virus.

“The same people they’re trying to protect are the same people who are sensitive to the chemicals being dropped,” said Bret Camp, health services director for Resource Center Dallas.

One open letter signed by 26 doctors and other experts in 2001 said the chemical agents used in aerial spraying contain neurotoxins and can be dangerous to the treated area. The letter, distributed by groups opposed to mosquito spraying in New York City, specifically listed “immunosuppressed individuals, such as patients with AIDS and cancer,” among those who may be especially vulnerable.

“INDISCRIMINATE AND UNNECESSARY SPRAYING OF ‘FRIENDLY FIRE’ PESTICIDES, ESPECIALLY IN HEAVILY POPULATED URBAN AREAS, IS FAR MORE DANGEROUS TO HUMAN HEALTH AND THE NATURAL ENVIRONMENT THAN WEST NILE VIRUS,” the letter states. “THE HEALTH OF MANY PEOPLE IS DETERIORATING AND WILL FURTHER DETERIORATE, SOMETIMES SERIOUSLY, AS A RESULT OF EXPOSURE TO ‘FRIENDLY FIRE PESTICIDES’ USED IN THE CHEMICAL WAR AGAINST MOSQUITOES. THOSE WHO ARE ESPECIALLY VULNERABLE INCLUDE CHILDREN, THE OFFSPRING OF PREGNANT WOMEN, CHEMICALLY SENSITIVE OR IMMUNO-SUPPRESSED INDIVIDUALS, SUCH AS PATIENTS WITH AIDS AND CANCER, AND THOSE SUFFERING WITH ASTHMA AND OTHER ALLERGIES.”

West Nile-infected mosquitoes found in Oak Lawn; crews to spray area on Monday night

The map above shows the area in Oak Lawn to be sprayed Monday, June 18 beginning at 10 p.m.

 

Mosquitoes carrying West Nile virus were found in the Wycliff/Maple area in Oak Lawn and city crews will spray in the area for mosquitoes on Monday night.

Because of a mild winter and wet spring, West Nile virus is active two months early this year and has been found in mosquitoes in 10 areas in Dallas.

The city will spray the area from 10 p.m. Monday night to 3 a.m. Tuesday morning.

West Nile virus can be particularly dangerous to people with HIV.

“West Nile is a concern to HIV-negative and -positive [people],” said Bret Camp, health services director for Resource Center Dallas. “Any co-infection has the potential to exacerbate the situation and make someone have a more serious condition.”

During the overnight spraying, keep pets inside, vehicle windows up and don’t follow the trucks, Dallas city spokesman Jose Luis Torres said.

“The truck sprays up, shoots 180 degrees and it spreads like smoke,” Torres said.

He said if anyone comes in contact with the spray, wash with soap and water.

The area to be sprayed is bounded by Maple Springs Boulevard, Mahanna Street, Maple Avenue, Wycliff/Douglas Avenue and Lemmon Avenue.
