SOUTH RUSSELL, Ohio - First collected in Allentown, Pennsylvania in 1998, the Brown marmorated stink bug (BMSB) was named an invasive species by the National Invasive Species Council (NISC) after being discovered thriving outside of its native habitat.
Normally found in its native range of Taiwan, Korea, Japan and China, the brown-colored stink bug has been making Pennsylvania, Ohio and many other states its new home. Experts believe the Asian species found its way to the United States much earlier than 1998, most likely by seafaring ships.
Case Western Reserve associate professor Mark Willis said he and his colleagues have collected many of the Asian stink bugs, but they aren't much different than those that have always been native to Ohio.
"There is a group within this big collection of insects called stink bugs. There are a lot of other closely related insects that also have defensive glands that are also very willing and able to smell bad when they get threatened," Willis said
More annoying in the fall through spring months, the bugs seek warmth and safety from predators in homes, wooded areas and anywhere out of cold elements.
Facts on Asian-native stink bugs from the NISC:
1.) Emerge in spring, deposit eggs in summer.
2.) Feeds on wide variety of host plants, ornamental and food-bearing. Fruits attacked include apples, peaches, figs, mulberries, citrus fruits and persimmons.
3.) An agricultural pest in Pennsylvania.
4.) Are not harmful to humans.
5.) The stink bug will not reproduce inside structures or cause damages.
6.) Typically, stink bugs will emerge from under cracks, under or behind baseboards, around window and door trim, and around exhaust fans, or light fixtures in ceilings.
7.) Prevent invasions by sealing openings with caulk, or other suitable materials to prevent the insects from crawling out.
8.) Sweep up dead bugs instead of vacuum. The vacuum may acquire the smell of stink bugs for a period of time.
