I think that SHB is pretty much ubiquitous to the US now... :roll: Although if you are a bit secluded they might not find you. The best defense is a strong hive. Those one or two beetles can become a wriggleing mass of slimy demon spawn really quick if the hive stumbles for some reason. That being said, it isn't common for a strong hive to get knocked back quickly.
I've seen more this spring than ever before, despite the cold winter, although I had 9 hives survive, the first for me. I see occasional shb larvae on the bottom trays, and occasional moth larvae, but never in the hives. Except the observation hive, where it doesn't get below 65F...
