Stink Bugs are an overwintering pest that are most commonly seen in early fall when temperatures start to drop as they look for shelter, then again in the spring as they emerge to get back outside. 

They can fly and leave a cilantro- or skunk-smelling odor as a defense mechanism, and they may even produce allergic reactions (rhinitis and/or conjunctivitis) in individuals who are sensitive to the bugs’ odor. They do not bite or spread diseases, but they can cause significant damage to crops in large numbers.
