Survey and Treatment Projects

The Oregon Department of Agriculture placed almost 13,000 spongy moth traps statewide in 2022. Seven spongy moths were detected in Benton (3), Clatsop (1), Columbia (1), and Washington (2) Counties. A high density of traps is being placed around these catches in 2023. The Oregon Department of Agriculture is also continuing to place a high density of traps in 2023 around the 2020 flighted spongy moth trap catch on Sauvie Island and around the 2021 spongy moth trap catch in Umatilla County.

The USDA completed an environmental assessment for this project prior to treatment.
