DALLAS - Dallas County health officials say efforts to reduce the mosquito population in the county have been successful.

Tuesday, officials said areas the county began spraying last week, including DeSoto and Lancaster, have seen a reduction in the mosquito count by as much as 60 percent.

Monday night, crews started starting spraying in Dallas and more spraying is scheduled for Tuesday and Wednesday nights.

We're looking at mosquito abundance, said Zachary Thompson, director of the Dallas County Health Department. Dr. Perkins has identified areas weekly where we're seeing an increased number, high counts of mosquitoes. We think that the targeted spraying is going to work in knocking down the mosquito abundance.

However, they have not yet been able to spray in Duncanville, where there is large count of mosquitoes. A decision on whether or not the city will participate in spraying will take place at a council meeting Tuesday night.

So far this year, there have been no human cases of West Nile reported in Dallas County. Officials are encouraging residents to keep gutters clear of leaves and debris to reduce the amount of standing water.

Data from recent spraying in Dallas is expected at the end of the week and will reveal how successful county efforts have been.
