Help Find the Stink Bug

AUGUSTA – Entomologists at the Maine Department of Agriculture, Conservation and Forestry (DACF) are seeking public assistance locating the brown marmorated sting bug (BMSB). Recent posts to the DACF’s Maine Bug Watch Facebook page have state officials interested in the prevalence of the BMSB in Maine. The bug is a major agricultural pest in other states and has caused severe economic damage to a number of crops in the mid-Atlantic states. 

To help determine how widespread the brown marmorated stink bug is in Maine, and the risk posed to Maine agricultural crops, the Department is asking residents to report sightings of this pest through an online report form: A photo is required to verify the identity of the bug (there are other bugs that look like it), or bugs can be captured and frozen, with an email report sent to

Brown Marmorated Stink Bug

Originally from Asia, the brown marmorated stink bug was accidentally introduced into the mid-Atlantic region of the United States in the late 1990s. It has since spread to 44 states. Like other familiar home invaders, the Asian multicolored lady beetle and the western conifer seed bug, BMSBs usually enter structures around early fall to seek a safe place to overwinter. In many states south of Maine, the numbers of stink bugs entering homes can be startlingly large. With the range of the brown marmorated stink bug expanding northward and westward, it is not unreasonable to expect that many Mainers will start to see large numbers of this bug.

As a home invader, the brown marmorated stink bug is merely a nuisance. The bug will not harm people, pets, or structures. In neighboring New Hampshire, where it has been an acknowledged nuisance pest for 3-4 years, control efforts have been recommended on an orchard crop this year for the first time.
