Who are we?

Four Rivers Vector Control District is an Oregon Special District that was formed by petition in 1985. The District was established to monitor and control mosquito populations in order to reduce the risk of mosquito-borne diseases, such as malaria, dengue fever, Zika virus, and West Nile Virus. Four Rivers Vector Control District conducts surveillance to monitor mosquito populations, identify potential breeding sites, and implement control measures such as larviciding, adulticiding, and source reduction to help reduce the number of mosquitos and prevent the spread of diseases.
