Hello Mike,

I would think and expect that small time beekeepers have much more time 
to do these things carefully than the professional beekeepers that have 
to go from yard to yard and in the shortest time possible place or 
remove their pollen traps (and havest the pollen). The proffs would 
certainly not have the time to alternate between pollen traps in place 
and bypass every other day or so, they would let them sit there much 
longer. So what you read much be for the hobby beekeepers like me (and I 
presume you).
