They’ve become as sure a sign of spring’s arrival as the chirping of the birds and the blossoming of trees. The Brown Marmorated Stink Bug (BMSB) has only been on the continent for a couple of decades, but has managed to hitch rides in nearly all US states and Canadian provinces.
The first official detection of the bug in Canada came in 2012, when a homeowner in Hamilton found one on his property. Since then, the presence of the invasive species has been confirmed in Toronto, Vaughan, London, Ontario, Fort Erie, Ottawa, Windsor, and several other provinces. US authorities have confirmed the stink bug’s presence in 36 states and the District of Columbia, posing serious agricultural threats in six states (Pennsylvania, West Virginia, New Jersey, Delaware, Washington, D.C., and Virginia), and nuisance problems in thirteen others (Washington, Oregon, California, Kentucky, Indiana, Michigan, Tennessee, North Carolina, Ohio, New York, and several others).
