Uh oh! Your bug appears to be Halyumorpha halys, Brown Marmorated Stink Bug. Has brown shield-shaped body like other stink bugs, but is distinguished from other stink bugs by lighter bands on antennae and darker bands on the rear of the front pair of wings. Can become a difficult problem to control if sets up housekeeping indoors during fall-winter months and if disturbed, will emit an unpleasant and long-lasting aroma from its scent glands on the abdomen and thorax. Suggest you contact an entomologist at your local university to confirm its identity and if it is, to find out methods of control indoors and outdoors. There are Brown Marmorated Stink Bug pheromone traps available. They are a major crop pest damaging everything from squash, to apples to tomatoes.
