Mosquito Control in Port St. Lucie
Port St. Lucie lies inside the St. Lucie County Mosquito Control District, founded in 1926 and covering 301 square miles. The District manages impounded wetlands, uses mosquito fish and larvicides, fogs by truck and posts a fogging map for residents. Its advice is specific: dump anything that holds water twice a week when it has rained, and regrade low spots where puddles last four days or more. In 2025 UF/IFAS Extension St. Lucie County reported a newly detected species here, Aedes scapularis.
