Brown Marmorated Stink Bug (Halyomorpha halys) is a native of Eastern Asia and was first detected in Pennsylvania in October 2001. The insects often are found in houses, where they produce an unpleasant smelling chemical. They can be an agricultural pest, threatening apples, pears, peaches, figs, mulberries, citrus, persimmon and soybeans.
