Duke Energy’s two-man boat crews apply chemicals to mosquito larvae in standing water along Lake Norman shorelines annually from May to October. Duke encourages lakefront homeowners to avoid letting containers collect water on their property, since standing water can produce a brood of hungry mosquitoes within six to eight days.

Homeowners should empty clogged rain gutters, flower pot saucers, furniture and outdoor toys, fill tree holes with builders’ sand, clean bird baths regularly and empty beached boats.
