Living in the northern U.S. could soon mean having to deal with a lot of stinky and invasive neighbors. As the planet warms up, the habitat of invasive stink bugs could greatly expand through the nation's northern areas, a recent study found.  Brown marmorated stink bugs are known for terrorizing crops and swarming houses during winter months to escape the cold. And the tiny bugs pack a massive and pungent odor – if you kill them, a smell that many describe as being reminiscent of cilantro, and for some skunks, will fill the air.  The bugs have been detected in 46 states but are mostly populated along the East Coast from North Carolina through New York and along the West Coast. They're considered both an urban nuisance and an agricultural pest in 15 states, according to the study, published in Pest Management Science, but researchers found that their habitat could expand by 70% by 2080. It's expected that stink bug habitat will shift further north, particularly in areas in the Mid-Atla
