Heavy Rains Flush Away Much of Kentucky's Mosquito Population

Jul 11, 2013

The mosquito population is in a bit of a ‘flux’ right now.  It’s difficult to predict just how much bug biting will go on this summer in central Kentucky. From mid-July into early August, mosquitoes traditionally peak here.  But, heavy recent rainfall is flushing away mosquito larvae.  Fayette County Health Department’s Luke Mathias hopes such rain repeats itself on a weekly basis.

 “If we had rain every seven to eight days that would actually be perfect.  Of course, it wouldn’t eliminate mosquitoes to a large degree but it may help to reduce the numbers to where it was more manageable,” said Mathias.

The down side of all this rain, says Mathias, is it creates mosquito habitat in areas that usually dry out in the summer. 

The threat of West Nile Virus also appears smaller.  Mathias says there’ve been no cases of West Nile reported in the Commonwealth this summer.

“Nothing in Kentucky has been detected, at least at the last time I checked the site, but like I said Tennessee and I believe Ohio both for sure had some cases of West Nile already this summer,” said Mathias.

The Centers for Disease Control reports human infection of West Nile in Tennessee.  The same map shows also shows West Nile in all four adjoining states north of Kentucky….but no cases involving people.

Mathias says crews will continue spraying pesticides around Lexington.  He says such spraying usually continues up until the first frost of fall
