Can stink bugs bite?

Stinkbugs do not bite. 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.

Although stink bugs do not bite, they can be a nuisance. Stinkbugs secrete a strong-smelling liquid that repels predators. When stinkbugs invade a home, occupants usually notice their foul smell very quickly. Whenever a stinkbug feels threatened or disturbed, it secretes a sticky liquid that has a lingering smell. Stinkbugs are also harmful to many common crops. One of the most common stinkbugs in North America destroys plants in the mustard family.
