Brown Marmorated Stink Bug (BMSB), Halyomorpha halys

The invasive brown marmorated stink bug (BMSB; Halyomorpha halys) was first discovered in Pennsylvania in 2001, and has caused tremendous crop damage in many mid-Atlantic states. Two to three years prior to noticeable crop damage, BMSB may be seen overwintering in people's homes often in large numbers.

Reports of BMSB overwintering in Maine structures have been verified from 87 towns in 13 counties. Reports of overwintering populations help experts predict and prepare for subsequent potential crop damage.

If you believe you have seen this bug in your house, office, garage, etc., please take a photo of it and report here.

If you are noticing crop damage due to the brown marmorated stink bug, contact the Cooperative Extension Pest Management Office.
