i'd avoid spanish moss in general. i live in coastal georgia where everything is covered in spanish moss and while at times it looks pretty it is filthy, moldy, filled with bugs and the occassional anole (the one good thing that lives in it ). hopefully any spanish moss that you find bagged in a store has gone through some sort of disinfection/denastification process, but i'd rather be safe than sorry having seen the nastiness of it first hand.
