The Cedar Mill area is Ground Zero for the current Japanese Beetle infestation that threatens our local gardens and nurseries. Join your neighbors on Monday, March 6, at 5:15 pm, in the Library’s second floor meeting room for a free informational meeting presented by the Oregon Department of Agriculture. You’ll learn to identify the beetle, the various stages of its life cycle, and what you can do to help prevent the spread of this destructive garden pest. Additionally you’ll receive information on the proposed use of the pesticide Acelepryn that will be applied to our area in late April or early May pending funding and approval by the Director of the Oregon Department of Agriculture.

A native of Japan, the Japanese Beetle was first detected in the state of New Jersey in 1916. Since then it has slowly spread across the United States and, in fact, has been eradicated in Oregon several times in the last 30 years. While especially partial to roses, the beetle also attacks grapes, orchard fruits, cane berries, corn, hops, outdoor cannabis and urban forest trees. This latest infestation likely originated from infested plants that were transported in nursery stock. Once established, the infestation easily spreads. Even the simple act of depositing your grass clippings in yard debris recycling bins can broadcast the infestation far beyond your own garden.

At this time, a coalition of multiple agencies in Oregon is developing a plan of action using a science advisory panel consisting of experts across the United States. After carefully considering a number of options, a single application of Acelepryn is expected to be the most effective treatment for the 1000 acres affected in the Cedar Mill and Bethany areas. This low-risk insecticide is not harmful to humans or domestic animals and has been used in Oregon, Idaho, California, and Utah for Japanese Beetle eradication projects since 2009. The decision to treat our area will depend on receiving the needed funding to conduct the ground treatment operation, industry support, and community support. To learn more about the project, visit
