Charles,

Try wintergreen oil.   It is extremely potent (and expensive when you can find it).  Try a drop or two in the hive. 

I have not had any significant infestations this year (YET).   When I do, I will break out the wintergreen oil.   I am also going to try what the Aussies do with Chux wipe cloths.  I have not tried it yet, just read about it.

The nearest I can find here in the States is unscented Handiwipes.    Put a wet piece across the top bars  (see the below link).    The bees will start to shred it to remove it.   When they do, it becomes a "velcro" type trap for the SHB.    Any SHB which the bees run up to the top of the bars will get tangled up and trapped in the fibers and starve.    Not a magic bullet, just another tool in conjunction with the SHB traps.   Below is a link to one of the Google search results on SHB and Chux.
