Pointe stink bugs
The document discusses the brown marmorated stink bug invasion in the United States. It describes the identifying features of the insect, its life cycle with multiple generations per year, how its population has exploded by spreading to over half of Pennsylvania and many other states since first entering the US in the 1990s, and the challenges it poses with its ability to damage plants and infest homes without natural predators. The document provides tips for controlling and reducing stink bugs both outdoors on plants and barriers, and indoors through treating cracks and crevices along with well-timed exterior treatments in late summer.
