During the early fall, while it’s still warm, you’ve probably seen this insect and its name sounds like what it's the most famous for: the stink bug. They are also known as shield bugs because they somewhat resemble shields. They are not harmful to people, but they will emit a strong smell if crushed or bothered and they can destroy fruit and vegetables.
Stink bugs are small and come in a variety of colors, but one of the most common ones is the Brown Marmorated Stink Bug (BMSB), which is brownish in color with white markings. The BMSB is brownish and has whitish or gray spots. They can congregate in great numbers on trees and plants and the greatest risks stink bugs pose are damage to gardens and commercial farms.
Stink Bugs have been around for a long time, but had a very nice life in Asian countries such as China, Japan and Taiwan. However, they are very good at hitchhiking in shipping containers. Suddenly, in 1998 a Brown Marmorated Stink Bug was collected in Allentown, PA. That was all it took for the invasion to begin.
Stink bugs reproduce fast and soon these bugs were showing up all over the east coast and then swept south. After that, they began spreading west across the United States.
