Physical Characteristics of Stink Bugs
Fully grown stink bugs are only 1/2- to 3/4-inch in length with a distinctive shape resembling a shield. Stink bugs are monochromatic in appearance, featuring an overall brownish-green color.
Stink Bug Behavior through the Seasons
Warm spring temperatures bring stink bugs out of hiding to mate. Female stink bugs can lay as many as 400 eggs, which hatch within a week and reach full growth by five weeks. As the weather cools off in the fall, stink bugs begin their search for warm winter homes.
Where Do Stink Bugs Come From?
Stink bugs are native to Asia. It’s believed they were accidentally introduced to the United States in Allentown, PA, where they were first sighted in 1998. While stink bugs have since migrated to various parts of the country, they’re principally concentrated in New Jersey along with several other Northeast and Mid-Atlantic states.
Since stink bugs are herbivores, they don’t pose a safety threat to humans. Their nuisance factor comes primarily from the nasty odor stink bugs emit when crushed.
