SCCMAD's mission is to safeguard the health and comfort of the citizens of South Cook County through a planned program to monitor and reduce mosquitoes and other biting insects that transmit diseases or parasites from one human or animal to another, known as vectors.
SCCMAD's Board of Trustees set the following operational policy in 1955 and it still remains unchanged today:
The South Cook County Mosquito Abatement District will abate effectively and economically the mosquito problem, using modern, scientific, and practical methods of control applied in an orderly and systematic manner while giving due consideration to the rights of property owners, residents, and political subdivisions of the District.
