My grandma got some kind of contagious bugs that can t be seen about 10 years ago. She transferred them to my parents and sister by being in their home, cars, touching, etc. They used permethrin, dandruff shampoo, etc. If you got to them right away you could wash them away with a shower and washing your clothes. However they spread through my parents house where my sister lives and she can t get rid of them. My mom sent a fur trimmed coat over here 5 years ago and it stayed in the closet until I put it on March 23, 2014. I felt all itchy and was worried I had bugs but my sister said she didn t think the bugs could live 5 years. She and my parents knew they could live a couple of years on washed blankets that were stored away in a garbage bag because they had gotten infected that way. Anyway I for sure have them from the coat and it s been 1 month. My other sister caught them from me 3 weeks ago. My house and car keep re infecting me even though we steam everything we can all the time. I ve used permethrin 31/2 tubes and AM VERY SICK FROM IT. I just got re infected on Easter by running the vacuum the 1st time since the initial cleanup. My family has misled me on what kills them like vinegar,dandruff shampoo, hair dye and cattle spraying my house and car. Help! What can live w/o a host that long. I feel as though I have resistant Norwegian scabies but everything says they can only go 36 hours w/o a host. Can they feed off of shed skin cells and off the fur ruff leather? How do I know what they are and how do I eradicate them from all my papers, books, and every nook and cranny?
