Orange County Mosquito Control has stepped up surveillance and targeted treatments in affected areas after Florida health officials warned of increased West Nile activity and confirmed a locally acquired dengue case.
Those operations will continue until surveillance shows the elevated risk has passed, with officials saying rapid response is focused on places where mosquito populations or illnesses have been identified.
A teaspoon of standing water left for more than a week can become a breeding site, prompting residents to inspect properties weekly, empty or cover water-holding items, and keep screens intact.
Orange County and the local health department also urged EPA-approved repellents, protective clothing and 0.5% permethrin on gear—not skin—while asking residents to report mosquito problems at 407-836-3111 or 3-1-1.
