The brown marmorated stink bug is native to Asia. It was introduced to the U.S. in the late 1990s and spread to Oregon in 2004.
The insect feeds on a wide range of plants, particularly vegetables, pears, apples and hazelnuts, but also ornamentals. This invasive pest is well established across Oregon, where it remains a threat to agriculture and a nuisance for honeowners.
Its name describes the odor they emit when they’re crushed. The insect shows up in homes in fall.
For more information on identifying stink bugs, see the Oregon Department of Agriculture guide to stink bugs of Oregon.
