After learning about Push-In queen introduction cages at the WAS-93
conference at Simon Frasier, I've never had a rejection.  I suppose
this cage may be too much hassle for a large commercial operation,
but I suspect the increased acceptance rate makes it worthwhile even
for many of these folks.
 
I think the fact that the queen gets to start laying, producing
laying-queen pheromone instead of caged-queen pheromone, makes a
big difference.
 
A tip from a sideliner in our local club: do queen transfers in the
cab of your pickup (or other confined area) in case she gets loose
and decides to try her wings.
