Yes, I heard a beekeeper give a little presentation on SHB. He swore by pickling lime in baitable beetle jails. He had pictures of the good results he had got. I tried it and didn't have the same luck. Perhaps I missed something in the presentation. In addition to the pickling lime maybe you have to add something to lure them in? For me, the baitable beetle jails work better with oil in them, but I make a mess with oil sometimes.
