Stink bugs, on average, are just over half an inch long. They're brown or green in color and have a distinct oval shape that looks like a shield.
True to their name, stink bugs emit a foul smell when threatened or harmed. This makes them quite a nuisance, though they're not seriously threatening to humans. Stink bugs also damage plants and gardens, and they tend to die inside light fixtures, causing the surrounding room to reek with their glandular odors.
