Yep I have, just the cheap brown rice, Coles does a box of 4 or 5 pouches. I vacuumed the room I planned doing it in, sprayed Glen20 in the room also and wiped down the table and 50l storage container, placed the accessories under the tub on table. Waited 20 mins or so with door shut then took a shower, went back in with wet hair and sprayed scissors, syringe hands with alcohol,
Did everything very slowly under the container leaning a bit over the desk so I could fit hands through if that makes sense, had an 80% success rate
