Congrats on the brood. As for the SHB, Dr. Hood of Clemson University and creator of the Hood Beetle Trap was a speaker at the spring Virginia State Beekeepers' Association meeting. He suggested that 30 beetles was a threshold point for considering control measures. Here in my part of Virginia I've yet to see that many beetles at one time and if you can't hear it, I'm knocking on wood!
Good luck!
