Learn more about how we serve you and Franklin County

Mosquito population activity in Franklin County directly effects and impacts the public health and welfare of its residents and visitors in addition to influencing the comfort, recreational and economic conditions as well.

The Franklin County Mosquito Control District (FCMCD) was formed in 2003 but funding and operations did not begin until 2004. Franklin County consists of both rural and urbanized areas. The District was formed to provide service to all of Franklin County’s 1,300 square mile area which includes the incorporated cities of Pasco, Mesa, Connell, Kahlotus, and the unincorporated cities of Eltopia and Basin City.  FCMCD utilizes a fully integrated pest management program to control mosquitoes. This includes disease (virus antigen assays) and mosquito surveillance/monitoring (Biology) mosquito larviciding and adulticiding (Field Operations), source reduction and public education programs.

FCMCD employs four permanent staff members’ year round and eight seasonal employees during the months of April through October. The staff members of the FCMCD are members of the American Mosquito Control Association and the regional Northwest Mosquito and Vector Control Associations and strive to be leaders in mosquito control services and to be responsive to our communities and the people we serve.
