Bob, Doreen, Ellen, and all who haven't seem the mess borers can make:

A whole bunch of damage!  If the infestation is severe, and is not dealt
with before the borers complete their life cycles--they can eat most of a
good-sized clump.  But that's not the only damage--bacterial soft rot will
set in, at least in this climate, and complete the devastation.  The few
nubs of rhizome that survive both will then send up little shoots, trying to
survive--and they probably will, but it will be a couple of years before
they get back to bloom size.  Assuming the borers leave 'em alone the
following season, that is!

I'm not necessarily advocating Cygon, but a full-fledged borer invasion is a
major problem in my area.
