have you looked into the horse paste at tractor supply?I don't have the all over itchy-crawlies I think bc I keep a topical on at all times (manuka or clove oil or sulfur). But I am covered from neck to ankles with bites that are now small sores from scratching. The bites are in rows or shapes-- some "c"s, some circles, some horseshoes, etc. I had no bites for about 2 wks (ab a month ago) and thought the manuka cured me. Maybe the star anise was what helped. I don't know. I've had this 5 months now and can't hug my little child. But I'm workin on building my faith in God.
also i never had noticeable bites so we might be dealing with the same mites also your skin could possibly be reacting to all of the treatments you are using..message me healed and I would love to give you support
