This insect, notorious for its “smelly” reputation, earned its name from its tendency to release an odor from pores on the sides of their bodies when disturbed or when crushed.  This secretion protects stink bugs from predators. They are often fed upon by birds, spiders, assassin bugs and other arthropod predators.
Most are plant feeders (a few are predators). Farming areas can yield good numbers in crops like cabbage, cotton, etc. or in nearby roadside vegetation. Many species come to lights at night. Adult stink bugs of various species are active from spring through late fall.

Prevention:

To prevent stink bugs from entering homes and buildings, seal cracks around windows, doors, siding, utility pipes, behind chimneys, and underneath the wood fascia and other openings. Use a good quality silicone or silicone-latex caulk. Damaged screens on doors and windows should be repaired or replaced.
