Which agency is responsible for regulating aquatic pest control in Washington State?

The agency responsible for regulating aquatic pest control in Washington State is the Washington State Department of Agriculture. This department oversees various aspects of agricultural practice, including pest control management for aquatic environments. The regulation encompasses the use of pesticides, the monitoring of aquatic pest populations, and ensuring compliance with relevant laws and safety standards.

By focusing on aquatic pest control, the Department of Agriculture ensures that practices are sustainable and do not harm the state's natural resources or ecosystems. This includes setting guidelines for the application of pesticides in aquatic settings and providing training and resources for pest control professionals.

Other agencies, while they may have roles in wildlife protection or environmental quality, do not specifically focus on the regulation of aquatic pest control in the same comprehensive manner as the Department of Agriculture does.
