Prior to the formation of Leavenworth Mosquito Control District, the Lions Club of Leavenworth had undertaken the raising of funds for aerial spraying of mosquitos in the Leavenworth area. This spraying typically occurred shortly before the 4th of July. However, in the late 90's this practice began to be challenged. Spraying was suspended in seasons 2000 and 2001. In 2002 the mosquito numbers were high enough that the City of Leavenworth, combined with the Chamber of Commerce took responsibility for a final aerial spray prior to the formation of the Leavenworth Mosquito Control funded by the Lions Club. Meanwhile, Lion's Club members began the process of preparing for the Mosquito Control District to be put to the Voters and proposed funding through taxes.
Once the District formation had been approved, the Chelan County Board of Commissioners accepted applications for the initial Mosquito Control Board and appointed 4 Board Members: President, Secretary, Treasurer and Board Member #1, Board Member #2 was appointed by the City of Leavenworth.
The Board began meeting in early 2003 where it soon became apparent that District activities should also include larviciding vs spraying alone. The position of Program Manager was therefore formed and began in earnest in May of 2003.
During the initial years of 2004-2006, taxes were assessed based on property values. In 2006 it was determined that continuing such an assessment would require annual levy approvals and was therefore moved to taxation on a 'per parcel' basis.
The Leavenworth Mosquito Control Board meets monthly, March-November. These meetings are open to the general public. Please see the "Activity Calendar" page for more detail.
