What is a Mosquito Control District?

A Mosquito Control District is an area with set boundaries approved by the County Commissioners where the landowners have agreed to develop and administer a program for the abatement and alleviation of mosquitoes in their area. The purpose of a Mosquito Control District is to manage and control mosquito pests and prevent diseases such as West Nile and Equine Encephalitis while providing for the protection of humans, livestock, pets, songbirds, and other wildlife The County Commissioners appoint a mosquito control board that governs the district and create a mosquito control fund by levying taxes within the district to cover expenses and projects in the area.
