Duncanville City Council to Consider Action Regarding West Nile Virus

Filed under: City |

Duncanville’s City Manager, Dan O’Leary, met with Dallas County officials, and representatives from other Dallas area representatives concerning the West Nile Virus and Dallas County’s response.

Dallas County has planned for the aerial spraying of areas of Dallas County north of I-30. Spraying is scheduled to begin at 10PM on Thursday, August 16, 2012 and should be finished by 1AM the following morning. Planes will fly low, between 200-400 feet off the ground.

On Thursday, Duncanville Mayor Deborah Hodge signed a Declaration of a Local Disaster, which states that Duncanville has had four reported human cases, and one fatality.

In addition, the Center for Disease Control officials and the state’s Health Commissioner, Dr. David Lakey, are recommending that action be taken to initiate activities within Duncanville to reduce the mosquito population.

At the next scheduled council meeting the Council will consider two options for mosquito spraying, as recommended by the Center for Disease Control and State Health Officials:

  • Intensive community-wide ground spraying for three consecutive days.
  • Aerial spraying, as planned in the north part of the County.

In a yet-to-be-determined date, South Dallas will be scheduled to be sprayed, as well as Addison, Carrollton, Coppell, Farmers Branch, Garland, Mesquite, and Richardson. So far, Sachse, Irving, and DeSoto have chosen not to participate in the spraying at this time.

Lancaster was meeting in an emergency meeting on Thursday evening to determine if that city would be participating.

Dallas County has contracted with Clarke, who will be using an adulticide named Duet. Duetcontains two pesticides called Prallethrin and Sumithrin, and a synergistic compound called piperonyl butoxide which increases the effectiveness of the pesticides. Prallethrin and Sumithrin are members of a category of pesticides called pyrethroids, which in turn are synthetic versions of pesticides produced by plants called  pyrethrins. Pyrethroid/piperonyl butoxide mixtures have been recommended for UltraLow-Volume (ULV) mosquito control in New Jersey by Rutgers,  The State University of New Jersey. The U.S. Environmental Protection Agency’s (EPA) current evaluation considers pyrethroid-containing  products to be slightly toxic with minimal potential risk to people when used properly as part of an integrated mosquito control program.

Symptoms of over-exposure can include irritation to the skin and eyes, respiratory and nasal irritation, irritability to sound or touch, abnormal facial sensation, sensation of prickling, tingling or creeping of skin, numbness, headache, dizziness, nausea, vomiting, diarrhea, excessive salivation, and fatigue.

Duet has a soil half-life of 12 days and has an extremely low pesticide movement rating because it binds tightly to soil. It is also unstable in light and air and rapidly degrades in sunlight at the soil surface and in water.

The next meeting of the Duncanville City Council is at 7PM on Tuesday, July 21st at the Duncanville City Hall.
