Have you seen any stink bugs in your house? Over the last few years, the brown marmorated stink bug has invaded the southern half of the Lower Peninsula. The invasive species is more than just a nuisance. It’s a threat to crops, too.

Amy Irish-Brown, a senior educator at Michigan State University Extension, and Jim Engelsma, president of J. Engelsma Orchards, Inc., joined Stateside to discuss the characteristics of stinkbugs that make them so difficult to monitor, control, and predict.

If you've seen a small shield-shaped brown insect slowly crawling on the walls inside your home, you might be housing one of Michigan's newest invaders: the brown marmorated stink bug.

This particular stink bug doesn't harm humans. They don't bite or spread disease, but they do eat plants and tree fruit. Since they first hitchiked to the United States about 20 years ago, but weren't seen in Michigan until 2010, they have become a pest to farmers and gardeners alike.
