The answer to 'why is my stink bug odor' is that stink bugs release a foul-smelling odor as a defense mechanism when they feel threatened. This odor is caused by chemicals called aldehydes and is meant to deter predators. Stink bugs can release this odor if they are crushed, disturbed, or feel their safety is compromised.
The stink bug odor is typically described as a pungent, unpleasant smell that can linger for some time. While the odor is not harmful to humans, it can be quite unpleasant and difficult to remove from clothing, furniture, or other surfaces. Stink bugs are not dangerous to people, but their odor can be a nuisance if they invade your home.
