I stayed in a rental home about two weeks ago (5/21-5/23) for 3 days. Upon arriving I noticed all of the beds and box springs had bed bug encasements (which I was hoping was a preventative thing). On my last day there I noticed that there was white powder (I'm assuming DE) sprinkled on the wooden headboards of the beds. Before leaving I washed and dried all of my clothes and upon returning home threw away my duffle bag. I did have a book in the side of my bag that I visually inspected rather than throwing away...
About 5 days ago I noticed two bites very close to each other on my neck so I did all of my laundry. When I cleaned out the dryer lint from my bedding load, I found a dead brown bug, but it was super tiny and just the body so I stupidly didn't take a picture.
Yesterday my boyfriend left his white t-shirt laid out on my bed while we went to yoga. When we came back there was a black smear on his shirt that looked like a permanent marker line, that wasn't there before. He tried to wash it out but it wouldn't budge. I then started to inspect my bed and noticed some new blood spots, but neither of us have any cuts.
Here are photos of the spots I found yesterday: http://imgur.com/a/ofHR5
I found a few blood stains a month ago on my bed that I posted on here (David said they didn't look BB related), but here are those again: http://imgur.com/a/0KOwV - these aren't smeared like the new ones though..
I called the rental company to see if the house I stayed in had a bed bug problem (I read online ratings saying that a bunch of their other properties had bed bugs). The lady said that she "didn't see any record of a bed bug problem at that property" and asked if I was having an issue then hung up when I tried to inquire about the DE on the beds.
I don't know if I'm being paranoid since I saw the DE on the beds and from my past bb experience (4 years ago), but if these spots look like bed bug marks I definitely want to get an exterminator in ASAP since I stayed at the possibly infested house ~2 weeks ago and had other unexplained blood spots on my bed about a month ago.
