Since 1969, the Benton County Mosquito Control District has been providing mosquito control services for Benton County.
Besides educating residents on ways to control and eliminate mosquito breeding areas, the district checks and treats water sites looking for mosquito larvae, using mosquitofish, and spraying/fogging, among other methods to reduce and eliminate infestations of mosquitoes during the summer.
