Mosquito Control

Santee Cooper's mosquito control program, currently referred to as Vector Management, was housed in our first permanent building in the late 1930s. We were instrumental in the eradication of malaria from the region by 1950, and we continue to control disease carrying and nuisance mosquitoes.

The program utilizes an integrated pest management strategy to effectively control problematic mosquito populations at over 50 subdivisions surrounding lakes Marion and Moultrie. This approach allows for control over each stage of the life cycle of the mosquito. Larvicides and pupicides are applied to achieve control of these critical aquatic life stages of the mosquito. Adult mosquitoes that originate from areas where larval control is not practical or possible are targeted with the safe and responsible use of EPA-approved chemicals by certified licensed pesticide applicators.

Aquatic Plant Control

Santee Cooper's Biological Services unit is responsible for the identification and control of invasive and nuisance aquatic plants on the lakes.

Non-native and invasive aquatic vegetation like hydrilla, water hyacinth, giant salvinia and crested floating heart can have a detrimental effect on the lakes' ecosystem, which is why Santee Cooper is committed to controlling their spread. Treatments include use of the EPA-approved herbicides and stocking the lake with sterile carp that feed on hydrilla.

Please report nuisance vegetation to Analytical and Biological Services at 843-761-4101 or 843-761-8000 ext. 4564.
