St. Lucie County to Conduct Aerial Larviciding for Mosquitoes on Hutchinson Island Starting Monday April 1 through Friday April 5

St. Lucie County Mosquito Control District Facebook page

Hutchinson Island - Thursday March 28, 2024: St. Lucie County’s Mosquito Control District is scheduled to conduct aerial larviciding missions over mosquito impoundments on North and South Hutchinson Islands’ mangrove marshes starting Monday April 1 through Friday April 5, weather permitting.

A small airplane will treat saltwater mangrove marshes along South Hutchinson Island between Bear Point Sanctuary and the FP&L Nuclear Power Plant; a small area of North Hutchinson Island and a small section north of FAU’s Harbor Branch Oceanographic Institute to reduce emergence of saltmarsh mosquitoes.

Spreading granular larvicide along the marsh fringes helps to reduce mosquito breeding that could normally result as water levels rise. The eggs of saltmarsh mosquitoes can rest in marsh soil along the edges of the impoundments indefinitely, hatching once they are contacted by lagoon water. Once the water levels of the impoundments reach a controlled height, the water reduces further hatching by covering the soil that is prime habitat for the mosquitoes.

Fogging maps and schedules can be found on the district’s website at The Mosquito Control District is dedicated to protecting people, livestock and pets from mosquitoes and the diseases they carry.

Residents are reminded to protect themselves and their property in the fight against mosquitoes. To prevent mosquito bites, residents are reminded to wear light clothing that covers the arms and legs when jogging or walking in the evenings, as well as using mosquito repellent with DEET. Homeowners can also assist in the prevention of mosquito populations by practicing the “tip and toss” method of emptying containers that collect standing water around their homes and yards. Even a bottle cap of standing water can provide a breeding habitat for mosquitoes. Plants, especially bromeliads, can also serve as mosquito breeding grounds. However, there are commercial granules that can be purchased to help eliminate the threat.
