I happend looked out my kitchen window, about an hour ago. Just in time to see bees swarming around. They have landed about 60 70 feet. Almost strait up, no way I can get to them. I have a swarm trap about 80 feet back in the woods. I also have one about 10 feet away and 10 feet off the ground. I just put a nuc on the ground with a few frames of comb under them. I placed a nuc about 60 fet and 10 feet up with 2 frames and some comb. I I also put bee lure on every thing, Question should I put covers on nuc or leev them open?
