West Nile Spraying To Take Place As Scheduled
Posted Date: 4/16/2013 9:30 PM

The Richardson Health Department reports tonight’s mosquito spraying will take place as scheduled. This will be the first of two nights currently planned for ground spraying after tests returned four positive results for mosquitoes carrying the West Nile virus last week.

Spraying was originally set to take place Sunday night, but poor weather conditions forced Health Department personnel to postpone both Sunday and Monday night.

“Ground spraying at night is just one of our methods to combat the spread of West Nile virus,” said Richardson Health Department Director Bill Alsup. “We are actively treating for mosquitoes during the day as well. Specifically, we have been actively adulticiding and larvaciding pools, storm drains and other locations to also knock down mosquito populations. The ground spraying is another component to that approach, and is necessary to provide the one-two punch we are hoping will have the highest degree of effectiveness in helping to keep mosquito populations to a minimum.”

Crews will continue to monitor wind conditions as they spray throughout the evening, and will cease operations if weather conditions fail to meet guidelines set for the proper application of the insecticide.

The Richardson Health Department conducts ground spraying mosquito abatement operations only if sustained wind speeds are less than 10 miles per hour, if it is not raining, and if temperatures are forecast to be above 50 degrees Fahrenheit.
