Aerial Spraying Is Complete – What’s Next

Southlake started the month with aerial mosquito spraying in an effort to combat the West Nile Virus.  On September 1st and 2nd, planes from Clarke Aviation (the same company that Dallas County used in their aerial spraying program) covered Southlake with the mosquito adulticide, DUET. The City took part in Denton County’s state-funded aerial spray program after the County declared a West Nile Health Emergency.  Part of the City is in Denton County, making the entire City eligible for spraying.

Now that the spraying is complete, what’s next?  The answer is simple says Kyle Taylor, Southlake’s Emergency Management Coordinator: “Prevention and continued adherence to the 4Ds is one of the best ways to continue to Fight the Bite.”

The City has collected samples in several locations both before and after the spraying.  The results which should be available by next week, tested for the amount of mosquitoes with West Nile Virus and the total mosquito count in those locations.  Clarke Aviation, the company responsible for the spraying, told Denton County that aerial spraying can result in a 70-90% kill rate.

On August 27th, the City Council voted to allow aerial mosquito spraying within the City.  Spraying was originally set to take place on Thursday and Friday that same week.  But weather conditions prevent spraying from occurring on Thursday and on Friday for several cities in the southern parts of Denton County.  The Denton County aerial spraying program concluded early Monday morning when all of the cities that opted in were sprayed.

Southlake has recorded six human cases of West Nile Virus since July 24th.  It was June 22nd when the first mosquito sample tested positive for the West Nile Virus.

“We are fortunate to be able to partner with both Denton County and Tarrant County on fighting West Nile Virus,” said Taylor.  “Tarrant County is working with the City, testing the City’s mosquito larva samples, and we are also working with Denton County with aerial spraying and helping control the adult mosquito population.“

Taylor presented an update to the aerial spraying program to the Council at the September 4, 2012 meeting.   He told the Council that the City will make spraying results available as soon as they are released to the City.
