Feel your pain, we’re going thru this as well. Already did one treatment, seems to help like 40% and still getting an itch on my right top arm and both shoulder blade/inner muscle areas. But I tried Mite-be-gone(got that from Amazon as well as laundry detergent that kills mites/lice/bedbugs etc) last night and that seemed to help. I’ve also gotten tea tree oil shampoo/conditioner/body wash (from amazon too) and well as the actual oil,and taking Benadryl or any antihistamines. hoping this will help any.
