    My 2 year old son had a small cluster of black marks on his shin yesterday. I only noticed when I was getting him ready for his bath but they could have shown up during his nap earlier in the day. They were not there in the morning when he woke up. I wish I had taken a picture but at the time, I did not think of it and just washed them off with a washcloth in the bath. He and my 5 year old daughter have also recently shown single bite marks but I had not been concerned about those til now because they were single marks and rather small.

    My question is, do bed bugs ever leave fecal matter on skin? I have googled and only come up with pictures on mattresses, furniture and floors or walls. We were treated for bed bugs 3 times between mid-September and mid-October based on bite marks and a canine inspection (the exterminators never saw a single bug, cast skin or egg). The canine is supposed to return in December to inspect again but I am sort of freaking out if this means they could be back.

    Hi,

    Technically they can but it is not that common at all and you would almost certainly find faecal material in other places as well as the ones on the skin. Faecal traces on the skin would only be left close to a bite site if the bedbug defecated while feeding in order to ensure it received the maximum possible size of meal. This is called micturation and does not always happen which is why it is rare to see.

    Richard Naylor took an amazing picture of one doing this but it is the only such image I have ever seen.

    Thanks David,

    There is a little video here that shows the process you are describing:

    It defecates about 25 seconds in, while it is still feeding.

    speaking of fecal matter...I have not found any but I have found some dark spots on our carpet behind our bed frame. I cannot tell if it is paint (the wall behind the bed is painted a deep, dark bown) or something else. It's just a few spots. Do they usually leave fecal matter in the carpet? These spots look very smudged, not at all black, vibrantly stained spots like the ones I've seen in photos.

    Hi,

    Faecal traces are most commonly found around refugia or harbourage sites so away from the walls on carpets is not a common place.

    If you can post an in focus image we may be able to give you some input on the probability.

    David, I will send you those tonight along with my bed photos. I have a suspicion they may be in the basebaords where the carpet meets the baseboard since we cannot find them elsewhere. I have not however, found traces of any kind of matter on the crisp white basebaords either. I continue to vacum them and I am also having Terminex re-steam the baseboards and re-spray when they come for our second treatment.

    Thank you.

    I did not see any more marks on my son nor on his sheet or his crib. He does have one small bite like mark on his shin near where these dark marks were. And this morning my daughter's pillow showed up with a small blood-looking streak (http://www.flickr.com/photos/70692550@N04/6397325337/) that has me freaked out. I really just want this "is it? isn't it?" paranoia to be over!
