  IPM Requirements for Developers  

House construction photoIntegrated Pest Management is an effective and environmentally sensitive approach to pest management that relies on a combination of common-sense practices. IPM programs use current, comprehensive information on the life cycles of pests and their interaction with the environment. This information, in combination with available pest control methods, is used to manage pest damage by the most economical means, and with the least possible hazard to people, property, and the environment.

Thurston County's Pest and Vegetation Management Policy

In 1987, Thurston County Commissioners appointed a broad-based citizens committee to study the county’s use of pesticides and to recommend a policy to address their use. This was in response to a growing concern by many citizens on the use of pesticides by the county and its impacts on the environment, public health and safety. The resulting "Pest and Vegetation Management Policy" provides guidelines for county personnel who are involved with operations that are related to pests and vegetation management.

The policy does not govern private parties on private land or other government agencies, however, it serves as a model for others interesting in minimizing the use of pesticides.
