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.
Indoor-living stinkbugs come out of hiding as spring arrives. Homeowners often find them disturbing because of their size. Their bodies grow to be about 2 centimeters both in length and width. In addition, their legs reach out even farther from their bodies. As their name suggests, when in danger, stink bugs emit a foul smell from an abdominal gland.
Stinkbugs are also harmful to many common crops. One of the most common stinkbugs in North America destroys plants in the mustard family.
