The  Royal botanical Gardens in Burlington Ontario has a huge iris garden. 
They had  tried dormant oil with good success. the oil coats egg (of young 
borer) and  they can't breath through their skin, and die of suffoction. That is 
how  dormant oil works. It is one method of borer control they I sugest in my 
talks  to Hort societies.

The straight dope from some pros! Oh, this is beyond marvelous! Chuck,  when 
do they spray and how often, in relation to the spring growth or  whatever? Or 
do they do it before the snow falls? I assume they are using the  standard 
weight stuff, rather than the ultra refined product Jones and I know as  
I had never even seen a borer until some woman in the next block brought in  
a whole bunch of truly foul 'Nancy Orne" from a family spread in  Connecticut. 
Suddenly, one had borer. Showed up first in my white tectorum,  of all 
places. I dug a clump in October as part of a bed renovation project, and  out 
dropped a mature borer, all set to pupate! I put him in a pimento  jar of alcohol 
thinking I'd mail him to Lowe to photograph since the one  Lowe had on the HIPS 
page was all dark and this one was two inches long,  bright pink, with a 
chocolate colored head---oh, he was a splendidly  loathesome bug!--- but 
apparently dark is what happens when  you drop them in alcohol.
