Beetles can be moved in yard debris through the removal and movement of items such as sod and grass clippings. The risk of moving beetles is highest over the summer when adult beetles are emerging from the soil and moving around to feed and find mates.  Hungry beetles are extremely active during the summer months. Photo provided by Melissa Schreiner, Colorado, USA. 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.
For more information about the quarantine check back on our Prevention page for the most recent information.

Second Treatment Wrapping Up in 2018 Thank you to residents and land managers in Washington County (Cedar Mill, Bethany and Oak Hills) and Oakland area that have been helping the Oregon Department of Agriculture beat the Japanese beetle! The Oregon Department of Agriculture (ODA) is currently wrapping up a second treatment in year two of the Japanese beetle eradication project. Support from resident in the area has been very positive. Before treatment, the ODA received over 5,000 responses from residents allowing ODA and their staff to treat the properties, including 30 Homeowners Associations supporting treatment in common areas. Tualatin Hills Parks and Recreation Department and the Beaverton School District are also supporting the project and allowing treatment to parks and school fields. Applicator crews have said that residents in the area are expressing their support for the project, with many "Thank you’s" and "Get those beetles!". Thank you to all of the residents who are working with us to protect Oregon’s plants and agriculture from this invasive species!  Contractor applies granular larvicide for treatment in 2018. Photo credit: Christopher Hedstrom. 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.

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. |
