Sorry,  do not understand. Why would putting them in a cardboard box for 3
days get  rid of AFB?



When they swarm they fill their crops with honey before they leave. If the  
hive has AFB the stored will be contaminated with spores, some of which may 
 get into their new home. Given a few days to use up what they have brought 
with  them all the spores should have left their bodies and be embedded in 
wax or in  stores within that wax.  Separate the bees from that source of 
re-infection  and they should be ok for the time being. Don't forget to burn 
the box and  comb.
 
Thinking ahead, if the parent colony does have AFB, sooner or later, it  
will be come weakened or die. Then the new lot may rob them out and pick up 
the  disease again.
