The Oregon Department of Agriculture is asking all residents, landscapers, and waste managers that work in the yard debris quarantine area to adhere to the information below in order to comply with the quarantine to prevent the spread of both Japanese beetle adults and larvae:

Quarantined yard debris and material:

• grass clippings
• plants with roots or soil attached
• sod or removed turfgrass
• growing media (i.e. potting soil from raised beds or potted plants, NOT fill dirt)
• compost
• bulbs or tubers of ornamental plants
• mixed loads containing any of the above material (avoid mixed loads containing garbage and non-plant material)

Not necessary or acceptable materials:

• loads of only leaves in the Fall/Autumn
• tree limbs or prunings (no roots attached)
• shrubs prunings or clippings (no roots attached)
• fill dirt
• lumber or fence boards with dirt attached
• non-plant materials (for example: lumber, cement, gravel, and fencing)
• materials not on the list of quarantined debris or materials

Note:

• Compost and transfer facilities ARE NOT ALLOWED to accept yard debris from the quarantine area in order to prevent the spread of Japanese beetle.
• If possible, keep yard debris at the property or use a standard curbside yard debris bin. However, if yard debris must be removed from the property, bag and cover the load and take it directly to: Northwest Landscape Services, 1800 NW Cornelius Pass Rd, Hillsboro, OR - (503) 486-5154.
  • Summer Hours of Operation: Monday - Friday: 6am to 6pm, Saturday by appointment; Closed Sunday. CLOSED for the Fall/Winter starting OCTOBER 5th, 2018 at 6pm. Northwest Landscape Services will reopen APRIL 1st, 2019.
  • There is no charge for residents within the quarantine or their landscape companies to dispose of yard debris waste at Northwest Landscape Services.
• As of April 2018, the road signs on Saltzman Road, NW 143rd Ave, and other locations regarding the Japanese beetle quarantine have been removed. This does not mean that the quarantine is not in effect.

PLEASE NOTE: THIS POST IS AN ARCHIVE FROM THE 2017-2018 PROJECT YEAR.
Japanese beetles were first observed in Washington county in 2016. Subsequent trapping and risk modeling has determined that certain areas have a particularly high number of beetles that may hitchhike out of the area on high risk yard debris. To aid in successful eradication, Oregon Department of Agriculture (ODA) is working to contain the Japanese beetle population to a limited and manageable area.


ODA has enacted a yard debris quarantine as part of a multi-pronged approach to eradicate the Japanese beetle from Oregon. This quarantine minimizes their spread to other areas in the region by restricting where and how yard debris from inside the quarantine area is transported and processed. Two key containment strategies have been implemented: 1) yard debris in household curbside bins are covered and hauled directly to deep burial at the landfill and 2) yard debris picked up by landscapers is directed to be covered and transported directly to a designated yard debris drop-off site at Northwest Landscape Services, 1800 NW Cornelius Pass Rd, Hillsboro, OR. In 2017, approximately 2,000 tons of yard debris were successfully moved into a special deep burial zone at the Hillsboro landfill where Japanese beetles within the material cannot escape.

​Why a yard debris drop-off site outside of the quarantine area?

The Oregon Department of Agriculture, Oregon Department of Environmental Quality, Metro and Washington County worked closely and deliberated over site locations. They ultimately chose this site for a few well-planned reasons. First, the site was chosen as the lowest risk site. This means that the site has the ability to manage the amount of material transferred and has the lowest risk of spreading beetles to other areas through re-sale of compost, recycled soil, or other mechanisms. Additionally, this drop-off site is in the same county where the population exists, Washington County, and is in near other commonly used yard debris drop-off sites reducing the burden on the landscapers or homeowners.

What happens at the drop-off site?

​This is a FREE service for those with material from the quarantine area. The time the material sits at the drop-off site is kept short in order to minimize the chance of beetles escaping and re-establishing in the area. Each load is then moved to a deep burial site in the Hillsboro Landfill to join the curbside yard debris from the quarantine area that is picked up by garbage haulers. Project partners monitor the quarantined yard debris to ensure proper disposal of material. When residents and landscapers comply with ODA regulations, they are more likely to succeed in protection of Oregon’s agriculture and natural resources.

It is very important that beetles are contained within Washington County while treatment takes effect. Containment efforts are ramping up, with a quarantine on all yard debris still in effect and expanding in 2018. Residences will receive electronic notices from Oregon Department of Agriculture, along with other communications planned throughout the summer.

Summary of the 2018 Treatment
The ODA continued their relationship with General Tree Service to apply the same treatment as last year, a granular pesticide called Acelepryn G® which is a targeted larvicide that kills certain pests in their larval state in the soil. The granules are broadcasted on lawns and other landscaped areas, then it breaks down into the soil when it is watered in through rain or sprinklers. This pesticide is a “reduced risk” pesticide and is not considered a health threat for humans, pets, and other insects that don’t go through a larvae stage in treatment areas. According to the label, “Acelepryn G is recommended for Integrated Pest Management programs on turf and landscape ornamentals because it does not directly impact natural arthropod predator and parasitoid populations including ladybird beetles (aka ‘ladybugs’).”  Since the treatment targets certain pest larvae in the soil, the treatment with Acelepryn G® has no adverse effects on pollinators when applied according to the label instructions. For more treatment & health information, please visit our Treatment page.

A snapshot of the treatment area in Washington County

• The area includes about 2000 acres of public and private land.
• As of June 1, 2018, approximately 5,800 residences, 5 parks, and 5 schools were treated.
  
  

While there have been some delays due to weather, treatment has been able to be completed as scheduled due in large part to the hard work by application crews. A big shout out to the crews members and crew leads who are working long days, rain or shine, to make sure treatment is done correctly and on time.
