I have been attempting a trap-out of the crawl-space of an old house with little results. There is no access to the crawl space as it has all been sealed with concrete. The bees found a way in through a 1/2 gap in the wall. I used window screen and formed a cone shape for the bees to escape, but keep them from going back in. Outside the cone exit I placed a 5 frame nuc with good frames of drawn comb.
After two weeks of little to no bees in my box and several trips back to seal up holes in my extensive tape job around the cone, I was still seeing little interest. At that point, I placed a contained queen inside the nuc to lure the bees over. I also sprayed the frames of comb with sugar water and placed a small dab of swarm lure paste in the nuc. I expected to return after a few days with a nuc overflowing with bees. Today when I returned, it had only several hundred bees in the nuc. Due to time constraints, I had to pull the nuc today and I placed the frames of bees into an 8 frame deep, along with my new queen (mated, marked and clipped). I also gave the hive a frame of brood and larvae from a strong existing hive of mine. I misted them all with syrup so they could get used to each other since time did not allow for a newspaper combine. I then placed a syrup feeder inside the new hive and installed an entrance reducer.
So, do you all think I have a shot at this hive overwintering if we keep some sugar cakes or fondant on them all winter?
