Up to 30 area captains and 300 volunteers would conduct larvae surveillance and control efforts. Originally control measures consisted of aerial application of DDT, burning marsh grasses and chemical fogging to control adult populations. Through diligent monitoring efforts, mosquito control staff often found older methods of control to be unsuitable before government regulators descovered problems. For example, the use of DDT was discontinued because of its harmful environmental effects before government regulators banned its use. The Commission now employs up to 15 university students each year, most of which are biology students.
Environmental monitoring continues to be a major part of each year's efforts.
Control measures still rely heavily on field surveys for larva development but control measures continue to improve in their specific control of mosquito larvae.
