I'm very new to beekeeping, just installed my nuc 3 weeks ago. So far things look good, I've got lots of larvae. On the advice of the experts, I put the second deep on a few days ago. Also, I'm using a hive top feeder. Tonight, when I went to fill the feeder, I saw a small black beetle in it. I looked on line and in my books to either id or eliminate it as a SHB, but could not be sure. Do other types of beetles find their way in and out of hives? Is it possible, at this early stage, to already be facing a problem with this pest? If so, what's the best way to manage it?
