Well the bugs were back last night and I realized what they were/are. Not ticks at all but bed bugs. Talked to the Building Super and the exterminators are coming tomorrow and sent me some instructions which included vacuuming everything. I decided I'd put my mattress and box spring in vinyl so I could sleep tonight without getting bit. The mattress went OK--I killed a few--but then the between box spring and the frame it was just thick with them. And in a bunch of different areas. And then I remembered-when I came in there was this white powder on the floor that I had the engineer vacuum up and I realized that the problem has possibly been there the whole time. Tune in tomorrow, folks
