Great site here.
I get bit what appears to be 3 or 4 bites every 3 to 5 days. I have searched the bedroom and have only found 1 dead BB, no live ones, some blood stains. I some packlight monitors, but they are still in the mail.
From this I am deducing that the infestation is light, as I imagine the few culprits go back to their nest and sleep off the meal. Is that reasonable?
Also, I have a large shag carpet I got on CraigsList that I put into the bedroom about 6 months ago. I fear it might be the source, (didn't see any BB in there however) it being an exceptionally deep shag where I could see BB easily avoiding any DE treatment or detection.
I rolled the carpet up, left it in the bedroom a foot removed from a wall, and surrounded it with DE (I have a tile floor). I also DE the baseboards, around a wooden desk near the bed, and made a nice DE mote around the bed on the tile floor.
I also inspected the box spring, didn't see any BB, but nevertheless dusted it with DE and encased it.
I am willing to get bit for a few more weeks if this eliminates the problem.
What else can you do when you don't see the source?
