We've had sporadic sightings of SHB here in RI. They seem to come up with the packages. Right now anyway, they don't seem to winter well.
There is a local grant in motion to study the SHB here. Something like 50 bottom boards spread out to a sampling of keeps throughout the state . The bottom boards are supposed to be equipped with some sort of shield around the edges. I thought it was supposed to start last year but haven't heard much about it yet.
