On Sunday evening, four planes covered the remaining 226,000 acres to complete the first round of application in those areas of Dallas County participating in aerial spraying. Weather permitting, five planes will apply a second round of insecticide tonight to the entire target area of 362,328 acres.
Spraying will begin at 9 p.m. today in the city of Dallas, earlier in other participating cities. Residents in all neighborhoods of Dallas should expect spraying to occur sometime between 9 p.m. and 1 a.m.
Since the insecticide Duet only kills adult mosquitoes, the second round of spraying is intended to kill larvae that have hatched since the first spraying.
Representatives from the Centers for Disease Control will be in North Texas this week, surveying and analyzing the region’s efforts to combat the West Nile Virus and will make recommendations on how to proceed.
“Now that the aerial assault is showing positive preliminary results, we need to expand our assault on the ground and enlist residents to join the fight by draining standing water to cut off mosquito breeding grounds,” Dallas Mayor Mike Rawlings said in a release. “It only takes a little soil, compost or a few leaves, and water that stands stagnant for 1-2 weeks, to breed mosquitoes.”
