I know what eats Iris Borer, it's a very small parasitic Nematode called
Neoapledtanids, what a mouth full. Any way it is sold under the name Scanmask
and I used it a few years ago with great results, it did not kill the borers in
the rhizome that year but come fall when thay leave and go into the soil GOT EM.
for the next 2 years I had no borer sign at all and for the last 2 years only
slight damage in 4 or 5 clumps in new beds that were made after I applied the
Nematode's in areas where thay were never applied in the first place.
I plan to get and use these again as thay worked so well for me in the past
(went from 10 per sq ft to 4 or 5 per acre). Thay were priced a little high but
I feel it was money well spent. Check out local organic lawn care services for
this product as it is sold for controle of grub worms in lawns.
Let me know how it works for you as I would like some feed back from other
folks who have tryed this stuff to see if it works as well as I think it did or
if I was just lucky and all the borers in my yard died of some other unknowen
