Go back a few posts, Mary Jo from Fort Myers revived the thread because she has just had the same problem.
In the original discussion I posted a reference about gypsum being used but since the Extension service is involved in this new case I would be inclined to wait for their verdict. I'm not sure what "Truly Green" are planning to spray but I would hope Mary Jo's son has verfieid that they are legitimate (such as with the Better Business Bureau).
