Okay! So I am three weeks post-treatment, and have not seen any live OR dead bugs.
I have the occasional itch/"bite mark," but I was able to force myself to attribute it to other things until I woke up today and noticed a black spot where there was not one before.
Do these/could these be possible fecal stains? I don't know what else they would be, as I don't have a black pen/ink around my bed or anything. Thanks!
(I did try scrubbing it out with water and a washcloth, and it just spread a bit.)
