2022 Japanese Beetle Season Update

Greetings!

Here is our 2022 Japanese beetle (JB) season update.

Property treatments were completed in late July, while traps were finished being collected in October. This season we had snow in May, an unseasonably long and rainy spring, and consecutive days of heat in July. Weather can impact our ability to carry out our Japanese beetle treatments, causing delays, and rescheduling. We thank you for your patience and cooperation through this last years complicated JB season. Of those who responded to our consent letters over 96% consented to treatment this year!

For the 2022 season we successfully trapped 3254 Japanese beetles, which is over a 10%
reduction in overall beetles caught in 2021. From the 2021 granular treatments and 2022 foliar treatments, there was a 12% reduction in number of beetles trapped in 2022 within the 2021 treatment boundary. 2022 marked the first year that we reduced the size of the treatment area. This was possible because of your continued support, the hard work of our seasonal crews, and the assistance from our cooperators, General Tree Service (GTS), Best Buy in Town, and the Hillsboro landfill. 

Oregon Department of Agriculture (ODA) will be sending out consent forms for the 2023 season starting in late January of 2023. A reminder that we ask for consent from each residence in the treatment area every year. ODA appreciates your willingness and support to help our program. Each season, we get closer to our goal of eradicating Japanese beetle and protecting Oregon from this harmful pest.
