Use robber screens to protect your nucs and smaller hives from the larger ones.
They are simple to make. The principle is to have #8 hardware screen covering the entrance area and a way for the resident bees to come and go in an indirect manner. The residents figure out they can't enter/exit directly.
Robbers and wasps are so focused on the entrance they can't get to, they never learn how to get in.
