My personal observation is changing location or bottom board on a hive and  
even moving to another yard does not clear all SHB from my hives here in  
Georgia.  My experience is that SHB are attracted to hives that are  stressed by 
removing honey and excessive manipulations.  
 
I have also observed beetles relocating to freshly hived feral swarms  within 
minutes of shaking the bees into their new home and this continuing for  
several hours.
 
I've also had the experience recently of having several SHB landing on me  as 
I rendered my beeswax...they are readily attracted by scent of hot beeswax it 
 seems.
