I had the same problem in a hive last fall.  Hive-top feeder, not division board but the same experience.  That hive went into fall weak and subsequently crashed, supporting your hypothesis that it's mostly a problem for hives that are already weak.

I didn't try bleach, but vinegar did nothing at all to deter them.

I have problems with SHB again this year, though I have not yet seen them in any of the feeders.  Mechanical traps (BeetleBlaster, et al) are not keeping them under control anymore.  (And the diatomaceous earth in a CD case trap was a complete flop.)

For context, I am in northeast Ohio but there is a compost heap within about 10 feet of the hives.
