As the weather cools in fall, you might notice some unwelcome visitors gathering around your windows, crawling along your siding, or sneaking into your home. These shield-shaped insects are likely brown marmorated stink bugs, an invasive species originally from East Asia.

Although they can be frustrating to deal with, there’s some good news. These pests don’t damage your home’s structure, bite people, or reproduce indoors. They’re simply looking for a protected place to spend the winter.
