I have a deep box trap full of old black comb set in an old Pine tree. I look at it every week. For the past 2 mornings at about 10:00 am there are at least 20 to 30 bees at a given time coming in and out of the 1-inch diameter hole, and kind of clotting the hole. However my sense is that they don't act like an established hive with purposeful trips in and out. I thought I had caught a swam, but both days now in the afternoon I see maybe one or two bees and that's it. The location is pretty consistent with the amount of light it gets. My thought is at least bees in the area know of the existence of the box, and the chances are pretty good now?
