Here is a good write up;
"Bizarre Neurological Sensations of Lyme Disease"
All these crawling and biting sensations that people are experiencing and attributing to parasitic or scabies infection and coming to the conclusion that their Laundry and House is full of bugs that they have to deal with is possible but highly unlikely.
When you NERVES are INFECTED you get periphreal neuropathy, Crawling and biting sensations.
If your finding fibers and specs that look like parasites
to the naked eye, you need to look at them under magnification . They are most likely Morgellons debris that a trangenic bacteria made from your skin protein.
"Figure 5. A "black speck" removed from the skin in Morgellons disease is red and magnified 500x."
All this fretting over the laundry really isn't needed , get a pocket microscope on ebay for about $7. 60x min.
The fibers are not parasites
they are products of your skin protein , keratin is a tough protein, your toenails are made of it. the fibers are as tough as your toenails and made outa the same stuff.
The fibers could be contaigous for morgellons though because they carry the Bartonella/BLO infection that cause morgellons but you don't need to protect yourself from them because until you get your own infection down your the chia pet that is making them. When you cure your own infection the fibers in your house will be gone.
