Is there any kind of safe, natural, organic way to kill this fungus? Neither my dogs nor people have contracted this yet, but I just cleaned out my brooder and I've had the chicks (3-2 mo old) right in a heavy traffics grass area right outside my back door. my dogs are always sniffing and peeing around this area too. Is there any kind of safe, natural, organic way to kill this fungus? Maybe something I can spray over the grass?? And then what happens when we cut the grass?!?!! Ahhh! Help!!!
