The Brown marmorated stink bug (BMSB) is a true bug in the insect family Pentatomidae. It is an agricultural pest in its native range of China, Japan, Korea and Taiwan. Recently (in 2000), the BMSB has become a serious pests of fruit, vegetables and farm crops in the Mid-Atlantic region and it has been spotted in other states as well.
As with all true insects, it feeds by using its proboscis to pierce the host plant. The BMSB feeds on many ornamental plants, weeds, soybeans, corn, peppers, tomatoes, tree fruits and berries. Their feeding on tree fruits such as apples or peaches results in damage called, “cat facing,” and renders the fruit unmarketable.
Here in the U.S., there are generally only one generation hatched per summer, however in their native range, 4 to 6 generations could hatch in a season.
The BMSB also likes to share your warm home with you in the winter. Just like ladybugs and boxelder bugs, they will flock near your doors, waiting for you to open one just long enough for them to fly in.
As their name states their business quite clearly, don’t smash these guys or vacuum them up while removing them from your home. I use the ‘cup and card’ method of catching them and throwing them outside to avoid the smell!
