Noxious Weed Control

Noxious Weed Control Board


Our mission is to act as responsible stewards of the land and resources in Spokane County.

We will preserve the productivity and diversity of agricultural land and natural resources in the most cost efficient manner, from the impact of noxious weeds. We will also protect human health and environment by promoting the implementation of Integrated Pest Management control measures.
Identification and control of Class A weeds and Class B Designates weeds will be a priority and we will attempt to reduce the impact of Class B and Class C weeds to a lower level of significance. View our Noxious Weed List or our list of Weeds of Concern.

What Is a Noxious Weed?


They are non-native plants that have been introduced to Spokane County through human actions.

Due to their aggressive growth and lack of natural enemies, these species can be highly destructive, competitive, or difficult to control.

Noxious Weeds are Everyone's Problem


Noxious weeds are everyone's problem and they can not only reduce crop yields, and destroy native plant and animal habitat, they can damage recreational sites, clog waterways, lower land values, and poison humans and livestock.

The Spokane County Noxious Weed Control Board can assist you with identifying noxious weeds and give you advice on their control.
