Sounds like you may have hood traps???
AJ's Just drops between frames on top of frames
Hood trap mounts on bottom of empty frame.
Bees will most likely be clustered this time of year in NC and I don't believe the traps will be effective. Bees have to run and corral the beetles for the traps to work well and even then I have had mixed success using them.
