Thurston County adopted an
Integrated Pest and Vegetation Management Policy
(IPM) [PDF] to provide guidelines for County personnel who are involved with operations and provide advice related to pest
and vegetation management. The County defines integrated pest management (IPM) as an approach to pest and
vegetation control that utilizes regular monitoring to determine if and when treatments are needed. The approach
emphasizes physical, mechanical, cultural, and biological tactics to keep pest numbers or vegetation problems low
enough to prevent intolerable damage, annoyance, or public safety hazards.
Since the adoption of our IPM policy, the County has experienced many pest problems and has
successfully controlled them using much less chemical control than we would have with past practices. Our IPM
policy has provided a direction that encourages understanding pest problems better so chemical control
methods are less necessary and pest control is more successful. We have taken our pest research and have
produced a great deal of information that was originally intended for internal use by the County, but have
reformatted much of it for home owners and land managers.
Additionally, the County has requirements for Integrated Pest Management Plans for certain land development or land
use projects which are located in areas where the drinking water sources are vulnerable to contamination.
