Mosquito Control


The Mosquito Control Section provides a direct service to approximately 2,100 communities in 16 Maryland counties. The primary goal of this program is to prevent the occurrence of mosquito-borne disease in humans, pets and livestock. Mosquito control is an economic necessity in some parts of Maryland dependent on outdoor tourism during the summer. The program relies on surveys and monitoring of the larval and adult mosquito populations to coordinate control activities. Control techniques include breeding source reduction, public education, biological control and insecticide applications from aircraft or ground equipment.
