Well, in the bees defense, I did not use smoke. What I did was this. I installed the nuk. Then when they drew out comb on all of the new frames, I added the honey super which they were up in propolizing everything. The bees started hanging on the front bearding heavily so I thought they are out of room and I did not want them to swarm. So I just added them a second empty box of frames and now they are not bearding so much and I put the honey super back on top. And to be clear they do not swarm me. It’s just one or two guard bees that let me know that they do not want me there.
When I bought them, the guy picked up the queen with his bear hand and marked her for me. They seemed very calm, there were no problems.
