I get a large amount of yellow & white sticky stuff on my mouth all day. I have even gotten lesions on cheeks in my mouth, on tongue. I have had a strange skin condition that causes lesions on my face and limbs that take months to heal and they leave shallow holes and scars. I have seen mites but they are so tiny that no ones can see them, but I see similar things w/ my 60x microscope.
I also find these all over but a bit larger and they are all wrapped up w/ strings like cocoons on them. They appear to be clothes moths and they are on all my towels, blankets, beds and clothes. These are not the ones that bite me. The almost microscopic black or brown ones are the ones biting me.
