They are very much like fleas - various sizes - from black spec to larger - they jump about. I have felt them when they leave my skin - plus they bite.
Strange thing is that my skin doesn't itch very much - only tend to do so when there is an area dying off. After a bath the things are either dead at the bottom of the bath or clinging to the sides. Bleach, Peroxide, Rubbing Alcohol kills them on contact, but because they are in the skin - they somehow keep reproducing.
I was reading about Dimethicone - used in conditioners, Aveeno etc - so I am going to have a go at that. I need something until I next see the Dr. NYDA lice treatment also contains the product so will try it.
I have spend £100s of pounds looking for a cure for this horrendous infestation.
