    Hi.

    I have found some dark/black marks on my passive monitor. My bed has been non isolated for 3 nights and prior to that was isolated for 7 nights. I am very concerned they are fecal stains, but they also could be dirt. They only show up with a torch or with a flash camera. If you looked at it from afar, the monitor looks clear.

    I've attached pictures from far away and close up. I don't have an earbud to do the smear test but they seem to brush away easily.

    Pictures here:

    Please can someone urgently advise. Very concerned.

    Hi,

    These are not faecal. They are too particulate and have not absorbed into the detection skirt.

    If you look at the example images you will see how they sit as circles and partially raised (raised enough we teach blind people to detect this way).

    Hope that clarifies.

    Are there specific images of fecal traces on passive monitors?

    Do fecal stains move or come off the monitor if you touch them or does this mean it isn't one? Or do they absorb into the skirt?

    Hi,

    As written many times the detection skirt is designed to partially absorb. Once deposited they can’t be wiped away leaving no trace.

    Please appreciate that this product was fine tuned and perfected long before you knew what a bedbug was (mainly because in 2009 most were blissfully unaware of the issue).

    Hi,

    Thanks, I really appreciate your help and expertise. I am still struggling to tell the difference between new black marks or spots (potentially dust/dirt) and fecal stains. Is it worth buying the Bed Bug Blue Fecal Test Kit? Or can I send into the Bed Bugs Limited Office for verification? (And replace this monitor with a new one).

    Hi,

    Because of the specific way that faecal sits and absorbs onto the detection skirt Bed Bug Blue is not really needed, or should not be. Its an awesome product and no professional should be without it but in this situation I would rather you developed the "zen" to look at things calmly and thus follow these simple rules:

    1 - if it brushes off it aint faecal
    2 - unless its round or 98% round it aint faecal

    The example image below show you a very clear level of detail.

    Hope that helps.

    Hi David,

    Thanks. I'll take another look with that in mind and try to stay calm about it.

    As ever thanks for your expertise!
