  • The Brown Marmorated Stink Bug in New Hampshire

    • University of New Hampshire. Cooperative Extension.

    • As of February 2015, brown marmorated stinkbug (BMSB) has been confirmed in 20 New Hampshire towns/cities. With the exception of a confirmation on nursery stock (shipped several months earlier from Long Island, NY), no specimens have yet been found on any crop. The vast majority of specimens have been found on or in buildings. We need your help. We want to find out where BMSB occurs in New Hampshire. Let us know if you see this species in or on your New Hampshire home. Verbal descriptions are not much use, but clear, close-up photos or specimens are helpful. We want to track this insect in NH and how it builds in numbers.
