    Just looking for a confirmation that this is something that's a part of the material and not anything bb-related, but there are tons of black spots on the bottom of the shoes. Some are teeny tiny and some are larger dots.

    Thanks in advance!

    Not an expert but if the larger black spec (with knife pointing at it) -- if that piece is sitting on top of the fabric as it appears, that piece is unlikely to be fecal. If you have a presumptive blood test kit you can get a pretty good idea yourself, and pretty much rule out fecal with a negative result. With a positive result, you would then compare sample against known fecal pictures to rule out false positives.

    Don't take any actions until either a pro confirms or you test the sample per the kits mentioned.

    See "Useful Tools" section for "Bed Bug Blue" detection kit. Another, I have personally used is here:

    Both tests have received good reviews from the pros.

    The spot sizes seem to be really consistently sized and shaped. If these were bits of fecal matter that had been picked up, I would expect there to be larger and smaller bits of flake. This looks a bit more dusty.

    I'm not sure if it's coming up clearly in the pictures, but the black dots are absorbed into the material. When I tried to wash, wipe, or smudge, there was no movement. Couldn't get anything up for bb blue and I tried a few times. There are actually layers of the straw material over some of the tiny and larger dots that dont have black, so I'm hoping that thus means it's just part of thaf material.

    That's why I qualified my answer. The black spot with the knife pointing at it looked like it was sitting on top of the material. In any event, if you used it correctly, a negative with Bed Bug Blue seems to rule out fecal. That said if you seemingly can't pick up anything at all, I would defer to the manufacturer. With the presumptive blood test kit I used several years ago, you didn't have to lift a sample, but could actually drop the reagent right on the sample for a result.

    Thanks, Richard and Bon Voyage Appreciate the input. I can't find any pictures of fecal on a material like this, or else I'd find it easier to compare.

    I'm (trying to be optimistic and) interested to see what the experts say.

    You guys cracked me up...

    So my husband yelled at me and was able to rub some of the tiny black dots off (does that confirm dust/dirt?- The reason I didn't think so is because these are unworn/brand new shoes).... not sure if this gives more education, but anxiously awaiting an expert.

    Thanks everyone

    Hi,

    100% not faecal.

    The visual confirmation of faecal is the most tricky part of bedbug ID's and as such if you are not certain its best not to add any confusion.

    You do not need to have a visible picked up mark for the bed bug blue kit to work and despite inferences above I am yet to see the kit fail despite peoples best efforts to use it incorrectly. Some presumptive blood test kits are however extremely toxic and should be avoided for that good reason.

    Hope that helps.

    Good Morning,

    I don’t have time now to address all the misinformation and innuendo in your above post, but let’s start out with what could be termed “tainting the competition”.

    You say: "Some presumptive blood test kits are however extremely toxic and should be avoided for that good reason."

    Since the only other presumptive blood test referenced/mentioned here is the Phenolphthalein Presumptive Blood test (Kastle Meyer), I assume that is what you are referring to? That’s certainly the inference.

    Kastle Meyer is a widely used and accepted presumptive blood test in the forensic sciences. Much studied and analyzed. As to detecting bed bug fecal, this same test has been used and commented upon favorably here by both Lou Sorkin and John Furman (killer Queen). Certainly if it was "extremely toxic and should be avoided for that good reason" they would have pointed that out. I have used it myself and found it easy to use, quite up to the task, and was extremely helpful in putting my mind at ease by ruling out what I then thought were fecal stains.

    Do you have any evidence/studies to show that when used properly this test is “extremely toxic and should be avoided for that reason”?

    Do you have any evidence/studies to show that the active ingredient (Phenolphtalein) is any more toxic than the active ingredient in Bed Bug Blue?

    And lastly, since you are obviously recommending Bed Bug Blue and warning people off Kastle Meyer, shouldn’t you disclose your business relationship with the manufacturer of Bed Bug Blue?

    Richard
