Please be advised the Mercer County Mosquito Control office maintains no regular “spraying schedule” or "spraying list." These applications are only conducted in specific areas when deemed absolutely necessary and under the appropriate environmental conditions. These applications are done in order to bring mosquito populations to tolerable levels or to reduce the risk of mosquito-borne disease.
