I've never heard a single beekeeper I know in this area mention dealing with SHB. The other day though, I was shaking bees off of frames for extraction, and on one, just as I gave a hard jolt, I could swear I saw a shiny little black bug run across a corner. It was too late to stop the shake and I only saw it for a second and did not get a good look. I regularly see spiders in the covers, but never down in the frames and this didn't look "spidery". From my short glimpse it did look like pictures I've seen of SHB. Didn't go through the entire hive, but saw no other signs in the super. These are wooden frames with Rite-Cell. Hive is very strong.

Has anyone in the Bay Area had beetles, or heard of anyone who has?
