Pest NameDescription 
Brown marmorated stink bugBrown marmorated stink bugThe brown marmorated stink bug (BMSB) is an introduced species that is very mobile and spreading quickly across the United States. Both nymphs and adults are voracious feeders on a wide variety of plants, including small fruits, tree fruits, vegetables, and ornamentals. BMSB can also be a nuisance in and around structures. Large numbers of adults are attracted to the outside of buildings on warm fall days as they search for protected locations to overwinter. They may emit a foul odor when disturbed or crushed or when they collect in large numbers. Attics are common overwintering sites for large numbers of adults and they may emerge into the home during warm periods in winter and spring. BMSB does not cause any damage to structures, does not reproduce indoors, and does not bite. However, large numbers can be annoying inside the home.
