Most stink bugs are plant feeders and eat house plants. Plant-eating stink bugs also feed on weeds, grass, a variety of fruit and vegetables, and field crops like sorghum and cotton. A few species of stink bugs do not feed on plants but instead eat other plant-eating insects.
Stink bugs invade homes seeking shelter and warmth as the winter approaches. They enter through small spaces, like cracks or holes in screens, and once inside, they reside in walls or attic spaces until spring. Attracted to light and warmth, the bugs can often be found congregating on walls, windows and sometimes house plants as they attempt to make their way back outside once warmer weather arrives.
