Integrated Pest Management (IPM): Finding a Better Way

Integrated Pest Management (IPM) is an ecosystem-based strategy that focuses on long-term prevention of pests and combines biological, cultural, physical, and chemical tools to minimize health, environmental, and financial risks. Pesticides are used only after monitoring indicates they are needed according to established guidelines.

IPM uses extensive knowledge about pests, such as infestation thresholds, life histories, environmental requirements, and natural enemies to complement and facilitate biological and other natural control of pests.

IPM Policy

The City recently developed an Integrated Pest Management Policy. The purpose of the policy is to promote environmentally sensitive management of pests and vegetation across Sammamish and ensure City operations and contracted services prioritize environmentally sensitive pest management, while also addressing public health, safety, economic, and aesthetics requirements.

The City’s IPM Policy:

  1. Identifies safe, effective management tools for local species of plants and insects.
  2. Provides guidelines for City staff and contractors working to manage pests on City-owned property.
  3. Promotes education for local residents and business owners about natural yard-care techniques and pesticide alternatives.

How to get involved

The City welcomes community partners to join our efforts to reduce chemical pesticide use and promote environmental health. Contact Lisa Werre at
