    My apologies if this is answered elsewhere; I've not seen it so I'm asking:

    1. Is it possible to tell how long since a bed bug has fed based on appearance? The only ones we've found have been paper thin/flat...curious to know what, if anything, that means regarding level of activity.

    2. If a bed is isolated and not slept in for a period of two weeks, would any bed bugs on the bed make themselves known by trying to climb off and getting stuck in the interceptors?

    Thanx

    Hi,

    Sorry I looked at these the other day and could not come up with an accurate answer other than:

    1/ There are too many variables for this to be accurately done.

    2/ Not enough research on this subject has been conducted.

    Thanks, David. We got to six weeks before finding one three weeks ago, and that has me wondering where else they could be, or how long they can play hide-n-seek.

    Thanks again. I appreciate your time.

    1. Partial answer is that plump ones and more red in their gut have recently fed, less plump and darker material in gut is less than recent. Flat, dull, bodies means longer period of time since last feeding. See some examples of recently fed and various times of post-feeding at http://www.flickr.com/photos/lou_bugs_pix/
    I'm not aware of any image postings of fed and timed exposures post feeding.
    2. I don't know of any published reports as David mentions, but if apartment is vacant and there are no cues to attract bed bugs elsewhere, they might just stay on the bed.

    Thank you. The two we found most closely resembled the unfed in lower right corner of photos, with the exception that they were likely fifth instar (according to pco) and had very little noticeable dark spot in abdomen. Same for the two nymphs (2nd instar), thin and flat without prominent dark spots.

    Fingers crossed we've seen the last of them, and that our friend from three weeks ago was a straggler, not a scout.
