About a week or so ago, I saw a couple of bees in my back yard. I thought it might be fun to try to entice them to a nuc box I had laying around so I started to put out sugar water in an open top feeder and in a quart baggie. I put some LGO on a couple of q-tips in the bottom of the nuc and added one frame of foundation. As you can see in the picture, there's lots of action. Question.... how can I improve the possibility of them swarming to the nuc when it gets a little warmer?
