About us


The Jackson County Vector Control District was formed by a vote of the public in 1968 for the purpose of providing mosquito and fly control to county residents. Actual control measures began in the summer of 1969. Because we are special district acting under state authority as outlined in ORS452, we have our own budget that is made up of property tax revenues. The vector control tax rate is 4.29 cents per $1000 assessed value, so a property with an assessed value of $200,000 would have a tax of $8.58. We are governed by a Board of Trustees who are appointed by the County Board of Commissioners.

The early years of the district’s operation were dedicated to locating, mapping, and treating the many mosquito-producing sources in the county. Irrigated pastureland, log-ponds, and sprinkled log-decks accounted for most of the mosquito problems. As more people moved into the county, houses and housing developments were built bordering these sources making mosquito/human contact more frequent.

As some of these older sources disappeared with the downsizing of the logging industry, other problems developed such as the western treehole mosquito and the cattail-marsh mosquito. The district has moved its physical location several times throughout the years. In 1980 the district took over the 2.2 acre former Camp White National Guard Facility as their present location and in 1993 a new district office was constructed on that site.


The principle objective of the Jackson County Vector Control District is to provide a means to prevent mosquito-borne disease transmission. The secondary objective of the District is to prevent pestiferous levels of flood water species of mosquitoes. The benefits to the citizens due to the successful completion of these two objectives are:

  • Reduced risk of mosquito-borne disease
  • Freedom from mosquito annoyance
  • Increased yields of livestock and animal products
  • Improved water management and disposal practices
  • Increased use and enjoyment of our patios, parks, golf courses, vacation areas, and swimming pools by the relief from mosquito annoyance
  • Increased efficiency of employees in out-of-door occupations
  • Reclamation of land as result of water management with minimum harm to habitat of fish and wildlife
  • Attention toward mosquito control will reflect upon other unsanitary conditions requiring a community effort for corrections

Basic Principles

There are several principles used in the overall operation of the District:

  • Education, both in service and of the community
  • A program based on incorporation of permanent control measures aimed at progressive reduction of known mosquito breeding sources
  • Adult mosquito control measures are included as a secondary type of control, except under epidemic conditions
  • Entomological services are used to determine effectiveness of control operations, sources of mosquitoes, and species of mosquitoes
  • Pesticides are not applied to waters in the District which are frequented by waterfowl or which contain any game fish without first obtaining the approval of the Oregon Department of Fish & Wildlife
  • Mosquito-borne disease surveillance that includes adult mosquitoes and dead bird surveillance
