The brown marmorated stink bug is one pest that Washington residents can’t seem to shake from their homes this winter.
As of December, the pest has been detected inhabiting forests, people’s homes and devouring crops across 30 counties statewide, according to Washington State University.
Some people might be asking where stink bugs originally came from and how they managed to end up in the Evergreen State. To uncover more about the story behind stink bugs, The News Tribune spoke with insect ecologist Patrick Tobin, an associate professor at the University of Washington who studies invasive species.

It’s been over 20 years since the stink bug traveled from Asian territories and arrived in the United States near Allentown, Pa., where it was first detected in the country in 1998. Tobin and other insect researchers believe the bugs came overseas as stowaways on commodity-trading ships.
