I have heard that it is helpful if you trap the queen until she uses it. Following is my experience when I failed to trap the queen in the hive. I guess I won't use this technique, again.
A few weeks ago I received my first batch of HSC (small cell plastic comb). I trimmed some down to 6-5/8" box size (with a band saw) and forced the field force and their queen into a 6-5/8" deep, 5 frame nuc. The fit was tight, there were many bees. They have been crowded in there for 4 days, until yesterday when they decided to go elsewhere. They had started to use the plastic HSC comb for pollen and some nectar, they had even used some wax to smooth out slight imperfections in some of the molded comb, but the queen seems to have refused to use it. Now they are gone; I miss them, they were very productive and well-mannered bees, my next try I will definitely use excluders.
