I stayed at a hotel about 6 weeks ago and had mysterious black streaks show up on a pillowcase that I did not use. I recently found a small black dot on sheets in my home. This dot was the size of a dot you could make with a pen. I was able to scrub it off with a baby wipe. Is this fecal matter?
My family members and I have been getting small spots, usually single or in two on our hands and face.
How long should I wait before I get a professional inspection?
I'll post photos as soon as I can figure it out.
Thank you!
