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
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.
This is a friendly reminder to please keep a close eye on your pets or leave them inside on the date of your scheduled treatment. With many people home during the COVID19 pandemic we have also noticed an increase in pet interaction during our Japanese beetle treatment. We understand that this is difficult, especially since we are unable to knock on doors this year as a way to maintain social distancing. If you are unable to keep your pet inside, please contact project coordinator Ashley Toland at (503) 881-5198 or email email@example.com, and we will make arrangements to call you on day of treatment before we arrive on your property.
Thank you for your understanding during this difficult time, and for helping keep our crews safe!
The Oregon Health Authority (OHA) is leading the state’s response to COVID-19. Health officials urge good hand washing practices, covering our cough, and staying home if sick. Based on these recommendations, our Japanese beetle eradication project will adopt the following measures to reduce contact and exposure between you and our eradication team:
1) Our staff will practice good hand washing hygiene and handle any notifications left at your door with gloves following recommendations by the Centers for Disease Control (CDC) and OHA. Sick ODA employees will be asked to stay home.
2) We will contact you by electronic means—phone, e-mail, and text—to alert you about the treatment date of your property in order to practice social distancing. We will avoid knocking on your door to reduce physical contact.
3) Please unlock your gates on the day of treatment to reduce exposure.
We appreciate your continuous support and assistance for our Japanese beetle eradication efforts under these unprecedented times. Please feel free to contact project coordinator Ashley Toland at (503) 986-4638 if you have specific questions, but understand that response time may be delayed due to the current circumstances. Thank you for your understanding.
