Daox,
You and I are in the middle of the same project, just different houses. But, I found out that not all blow-in Cellulose insulation is the same. Google: 'cellulose insulation ammonium sulfate' and you'll see what the issue is. Unfortunately, Greenfiber cellulose insulation has ammonium sulfate as a treatment -

From what I have read and heard, a borate or boric-acid only cellulose insulation is the better product. Unfortunately, I haven't found anyone locally who will sell it to a homeowner.
FWIW,
Tim
