Brown Marmorated Stink Bugs In My House In Maryland

Over the past few winters, I’ve been finding increasing numbers of stink bugs coming in my Maryland home. The stink bug that I see almost exclusively is the Brown Marmorated Stink Bug (BMSB). This stink bug is not native to Maryland or even the US. It is native to China, Japan and surrounding countries. The BMSB (Halyomorpha halys) is an agricultural pest. Its exploding population is a threat to our food production which if numbers can’t be controlled, will make the price of many fruits and vegetables rise considerably.

Know the difference between this non-native species and our native stink bugs.

Many of our native stink bugs look similar to the BMSB. To be sure you found a BMSB, look at the antennae and around the perimeter of their back:

The antennae have alternating dark and light bands and when looking from the top, you will see dark and light banding along the edges of the abdomen. See photos.
