Have you tried pure tree tea oil? Have you read the study concerning mite die-off as a result of occular demodex when exposed to tea tree oil? I can find it again for you if you want..but I think if you google "tea tree oil" and "demodex" in google, it will come up. Castor oil is also effective at smothering mites, as I have used it recently it seems to be working. Just my simple suggestions! :)
