According to Orkin, stink bugs do not typically bite people. Their mouths do not contain any parts for chewing or biting. Instead, the mouth part of a stinkbug is a tube-like beak that the insect uses to suck the sap from plants. Even so, they are often considered pests because they feed on both ornamental plants, garden produce and crops. In addition, they sometimes find shelter inside houses for the winter, living inside walls or crawl spaces.
