By 2009, this agricultural pest had reached Maryland, West Virginia, Virginia, Tennessee, North Carolina, Kentucky, Ohio, Illinois, and Oregon] In 2010 it was found in Indiana, Michigan, Minnesota, and other states.
The brown marmorated stink bug was accidentally introduced into the United States from China or Japan. It is believed to have hitched a ride as a stowaway in packing crates or on various types of machinery. The first documented specimen was collected in Allentown, Pennsylvania, in September 1998.
I started noticing them ~2009. Before that time I did not see a one and I got here in fall 1981. They love the bean fields here.
