If you have eggs you have uncapped brood. Technically, eggs hatch into larva and larva are capped, incubated, and on day 21 worker bees emerge. But terminology gets thrown around.
What you are looking for is eggs, or larva, to get the smell of new brood. Capped brood will work, (just not as good). Nurse bees will come out to work this capped brood, but, eggs and larva require more attention, and consequently more nurse bees come out. That is what you want.
What you are hoping for is to fool the queen, into thinking there is another queen in this box that layed those eggs. She comes out to investigate and/or fight. She will stay for a while, lay some eggs to establish her dominance over this chamber. Then, she may stay in the trap for a while, or, return to the tree. The nurse bees and houskeepers come out to take care of the brood so it will incubate and emerge. When you insert the brood, cleaners, and fanners come out to clean the trap, and to keep the chamber at the right temperature.
Sealed brood is far better than no brood at all. I would not put frames of honey in the trap. You don't want them to use the trap as a place to store surplus honey.
