ST. LOUIS (KMOV.com) – The heavy rain from the remnants of Isaac in this weekend’s forecast will help with the drought but it will also help in the fight against the West Nile virus for a little bit.
The forecasted rains will flush out standing pools of water where mosquitoes are breeding, but what happens next is a bad thing.
“When the rain is done we are going to end up with pools of water,” Drew Hane, St. Louis County Vector Control, said. “And that is where the mosquitoes can breed.”
There is a bigger concern this year about West Nile virus compared to last year. In August 2011, four percent of the mosquitoes tested in the county were positive for the virus. This year, it has more than doubled to nine percent.
“We want you to look for any standing water and when it is really, really hot these mosquitoes can mature in as little as five days,” Hane added.
