Denton County Releases Aerial Spraying Results

September 19, 2012 –  Several of the communities with the highest incidence rates in Denton County experienced the most dramatic reductions in mosquitoes as a result of aerial spraying. Spraying was conducted by state contractor Clarke in portions of Denton County from August 31 to September 2. The full report can be found here.

The number of new cases of West Nile virus has decreased substantially since aerial spraying; however, it is premature to conclude that these results are solely attributable to aerial spraying. The Centers for Disease Control and Prevention (CDC) will release a comprehensive regional report on this year’s West Nile virus season in the fall.

It is important to remember that aerial spraying is one piece of a WNV control program. Ground spraying, larviciding, education, and personal protection are also vital aspects to prevention of this illness, and must continue throughout the remainder of West Nile virus season. Please visit the DCHD West Nile virus website (, or call the West Nile virus hotline (940-349-2907) for more details about symptoms, prevention tips, county-wide  contacts, reducing mosquitoes around your home, and disease statistics.
