Welcome to 2021 neighbors. This is Austin with the Oregon Department of Agriculture. I wanted to let everyone know we have finalized our Japanese beetle treatment boundary for 2021. If you are seeing this post, that means you are in it! Follow the link below to view the updated map and see what it means for you! Treatment is free and will follow the same process as last year with an additional foliar spray for some properties. Consent form information has been sent via email and postal mail so please return these ASAP! We will be sending out notifications again soon. Follow the link below to view the updated map and get the details! https://www.japanesebeetlepdx.info/treatment.html  We have officially wrapped up our 2020 season. I want to thank everyone who helped make this turbulent year happen.
Overall, 98.5% of you consented to treatment this year. With your help we treated 12,200 residences which came to roughly 4324.5 acres. This year we trapped 4,490 Japanese beetles in total; 4,218 in the Cedar Mill area. The overall number of beetles trapped in 2020 was down 42% from the previous year. There was a 58% reduction in the number of beetles trapped within our 2019 treatment boundary as a result of the 2019 granular and 2020 foliar treatments. We saw a 67% decrease within the boundaries of the supplementary foliar treatment. In order to eradicate this pest, we plan to continue our treatment next season. We will continue our aggressive approach in 2021 while we have the upper hand. We are currently planning our 2021 treatment boundary and will share it once it is finalized. We urge everyone to continue not participating in plant exchanges and to adhere to the yard debris quarantine to prevent the spread of the Japanese beetle. Again, we thank you all for your continued support helping Oregon eradicate the Japanese beetle. It wouldn’t be possible without all of you! Earlier this year, the Oregon Department of Agriculture’s IPPM program continued its multi-year effort to eradicate Japanese beetle. From April to June, ODA applied granular larvicide treatment, Acelepryn G® to over 12,000 properties in Washington County. Treatment primarily consisted of one granular larvicide treatment applied to all grass lawns and/or ornamental planting beds in areas where beetles were detected in 2019. Acelepryn G® is a targeted larvicide that kills certain pests in their larval state in the soil. This is a “reduced risk” pesticide and is not considered to be a health risk for humans, pets, or wildlife, including pollinators, when applied according to label directions.
In areas with high beetle density, the granular treatment (Acelepryn G®) were supplemented with a foliar spray (Acelepryn®). The foliar application has the same active ingredient (chlorantraniliprole) as the granular treatment, and therefore the same minimal risks. Properties within 200 meters of a Japanese beetle trap that collected 40+ beetles in 2019 were included in the higher density treatment area. The supplementary treatment was sprayed in late June to early July on non-edible ornamental trees, shrubs and plants that are known Japanese beetle hosts at over 800 properties. The spray has no known adverse effects on beneficial and non-target organisms including earthworms and honeybees. This pesticide was selected because it is considered highly effective, but also registered as a reduced risk pesticide under the EPA. The 2018 eradication resulted in a 56% decrease in Japanese beetle in 2019. ODA will have more information on the impact of the 2019 treatment when the Japanese beetle trap numbers are totaled in fall of this year. The impact of this year’s eradication will not be known until Fall of 2021. ODA plans to move forward with eradication operations in 2021, and next years eradication boundary map will be released in Fall of 2020. Thank you to the residents for your continued support in helping eradicate this invasive and destructive pest, especially during these uncertain times.

The yard debris drop-off site opens TODAY at Best Buy in Town Landscape Supply* *In previous years, Northwest Landscape Services (NLS) was the yard debris quarantine drop site, Best Buy in Town Landscape Supply (BBIT) is the new yard debris quarantine site. **The yard debris quarantine drop site is opening later in the season than past years, this delay is a result of the current COVID-19 pandemic. Best Buy in Town Landscape Supply 2200 NE Cornelius Pass Rd Hillsboro, OR - 503-506-6446 Hours for yard debris drop-off starting June 1 2020: Monday - Saturday 7 am to 4:30 pm Closed Sunday The redirection of curbside materials for deep burial at Hillsboro landfill began on April 1, 2020. Who needs to use this drop-off site?: This quarantine is in place to help stop the spread of Japanese beetle. Landscapers and residents with large loads of yard debris (materials that do not fit in curbside containers) within the quarantine boundary (see map below) must use this FREE drop-off site for large loads of yard debris that contains quarantined material (see list below). Residents within the treatment area can also continue to use their curbside containers for smaller loads of yard debris. All curbside containers are being re-directed to Hillsboro landfill for deep burial. Drop site instructions: Landscapers & residents within the quarantine boundary must enter Best Buy in Town Landscape Supply through the main entrance on Cornelius Pass and park in front of the main BBIT office. A customer service person will help confirm that the yard debris is from the Japanese beetle quarantined area and direct you from where to go next. The quarantine means all quarantined yard debris must be either:
Accepted Materials (Materials under quarantine)
Flyers to print and distribute to your landscaper and/or crew: Flyer in English Flyer in Spanish (español)  Map of quarantined area. Please note this area has expanded since from 2019.
