Local Governments Use Integrated Pest Management (IPM)

Many governments in King County use Integrated Pest Management (IPM) to manage insects, weeds and other pests along roads and in the outdoor landscape. IPM uses landscape design and maintenance practices to prevent pest problems. Pesticides might be used minimally as a last resort.

The King County Noxious Weed Board uses IPM to protect health and the environment, while working to preserve wildlife habitat, native plant species, and livestock on agricultural lands, urban and recreational acreage, and all other lands in King County.

The City of Shoreline (external link) won King County’s 2013 Green Globe Award for being a leader in pesticide reduction.

The City of Bellevue (PDF) uses IPM to manage its parks and natural areas.

The City of Duvall (external link) suggests that citizens follow an IPM approach by using natural yard care.

The City of Renton (external link) uses IPM to manage its facilities and grounds.

The City of Redmond Parks and Recreation Department (PDF) uses a comprehensive IPM approach to manage pests (weeds, insects and rodents) on city properties.

The City of SeaTac (external link) has an Integrated Pest and Vegetation Management Plan that directs all of their operations on public lands, rights-of-way and bodies of water to do so in an environmentally sensitive manner while addressing public health, safety, economic, legal and/or aesthetic requirements.

IPM in King County – a history

In 1999 King County and the City of Seattle announced a plan to eliminate use of the highest hazard pesticides by June 2000 and to reduce overall pesticide use on public lands managed by the city and county.

  • Also in 1999, a coalition formed between King, Snohomish and Pierce counties to address the role of pesticides in the listing of Chinook salmon under the Endangered Species Act. See the Tri-County IPM Policy, Guidelines and Final Report for a summary of the efforts of that coalition and the model policy.
  • The 1999  IPM Executive Order required King County departments to manage landscapes in accordance with the Tri-County (King, Snohomish, and Pierce) IPM Pest and Vegetation Management Guidelines and to develop agency-specific IPM policies for their own operations.

IPM in Seattle – a history

The Preliminary Evaluation of Pesticides Used by the City of Seattle (PDF, 304 KB), released in 1999, describes the approach for a preliminary assessment of pesticides used by the City of Seattle. It was later adopted by King County.

The purpose of the assessment was to prioritize pesticides for a phase-out in order to reduce use of the most hazardous pesticides. The pesticide lists below are best understood when viewed along with the assessment report.
