I found this bug in my apartment in Chicago. We had bed bugs in our house the previous year (but we thought we got rid of them). This bug was very small - maybe 2 millimeters in length. These photos are all of the very same bug (just different lighting).

Can you smell almonds? Bud bugs have a distinctive smell usually described as being "like almonds". –  Jack Aidley Aug 9 '13 at 10:34
No noticeable smell. –  bearMountain Sep 6 '13 at 16:20

This is a really old thread but just in case someone happens upon it, this isn't a bed bug.

I am not an expert but it looks like it's likely a book louse or psocid. See comparison photos of unfed first instar bed bug nymphs vs. psocids/booklice here: http://bedbugger.com/2008/03/04/booklice/ It's all about the shape of the head and body.

I agree, I've had book lice in my Fly lab before and this looks rather like it! –  GriffinEvo Apr 24 '14 at 9:56
Thanks for following up with this. I think you're right, the photo you linked to looks spot on. Actually, the lady in the apartment above us had lice one or two times during this period - so that must have been what I found. Actually, I'm relieved, I'd rather fight lice than bed bugs. Either way, our apartment seems to be bug free now. –  bearMountain Apr 27 '14 at 15:25

I'll give it a shot, but note that I'm not entirely certain: It's a juvenile bed bug, first stage larva. The size description and the general habitus fit, as well as the white color.

i'd say he got it right - better photo here: bedbugger.com/photos-of-bed-bugs-and-signs-of-bed-bugs I hear there are now drugs you can take that kill the bedbugs when they bite you, which might work better... –  shigeta Aug 8 '13 at 19:55
