For the person being plagued by SCABIES - I had something like scabies (never did figure out exactly what, the doctor was useless on this). I can suggest a few things that worked for me. Get some green plastic garbage bags and white plastic garbage bags. The clothing that comes off of your body goes directly into the green garbage bag to be washed after one wearing, likewise your towel after one use. Store clean clothing out of the dryer in the white garbage bags until you put them on. Keep the bags sealed and separated. Wash your body and hair with Meat Tenderizer mixed in your water and shampoo (you can just mix in your hand before soaping up). Get the unseasoned meat tenderizer so you don't end up smelling like garlic. The papain in the meat tenderizer dissolves the exoskeleton of the bugs and they die. This also works for fleas for animals. Rinse thoroughly - it will leave your skin and hair nice and soft. You can get a large (almost 3 pound) dispenser of tenderizer online for around 20 bucks from Spice Place. Cheaper on the whole than small containers from the grocery store. Also change sheets and pillow cases every night. Wash clothes and linens in hot water and 1/2 cup bleach. Borax is also good - 1/2 cup for each load. Vacuum carpets and mattresses like crazy. Put your pillow through a hot dryer cycle. And this is very important - you need to change the internal terrain of your body, then parasites will not be attracted to you. Stop eating all forms of sugar and refined products, msg, artificial sweeteners and all junk food. Take a high potency multi and B vitamin complex. Drink hot water and lemon juice first thing every morning and a few more times during the day and before bed. Eat fresh food - lots of veggies. Coconut oil is also a great remedy for scabies. You can coat your skin before bed, even massage into your hair at night and shampoo in the morning. You'll be healthier in the long run and parasites will completely lose interest in you. Read the posts here on coconut oil - it seems like there are posts regarding scabies.
You can get rid of them. Best of luck.
