    The fun never ends. I got a new mattress encasement and put it over the previous one because I thought previous one was infested. I saw this yellow mark today. I know its new because I put the encasement yesterday. I know fecal is black but I see in forums mentioned that nymph fecal can be yellow. Hence checking. I did the bed bug blue test which was negative for fecal but the amount is so small (negligible) I am not sure it will even detect.

    Please advise

    Jim, Thanks for your response as always. The mark may look big because of the zoom. Here is the picture compared to a penny. Look pretty small right? Possible its uric? Thanks

    Don't think so. Uric stains are usually going be near the harborage, where there's plenty of fecal staining, egg deposition, and bugs. I think I have a good photo on my facebook page.

    Jim, Thanks for the response. I dont mean to challenge you (this is just paranoia), you are the expert, but is there a reason that the nymph wont defecate uric acid on encasement near the host. I have seen all the discussions that other including you and Dr. Sorkin have had on uric acid. It seems like Dr. Sorkin says in one of the threads that uric acid is the first thing 1st instar nymphs dump before feeding. Could this be a 1st instar nymph dumping or they do it in the harborage area only after coming out of the egg?

    Any other signs that this is not uric acid?

    Thanks as always

    Thanks KQ. You don't think this is ueric fecal? I just can't think what else it could be. Although I would kill for it to be not bb related

    Bump. Apologize about trying to headline this. But can some other experts like Dr.Sorkin content on ueric being seen outside of harborage areas. Thanks everyone.

    Good Lord!!

    You asked for an ID ... You got it and than question again if I think its uric acid or not. PRO's don't like the back and forth or when you try to get another answer to the same question. We wouldn't answer you if we didn't know what we're talking about.

    Your stain in question has nothing to do with bed bugs. It's not even close in color or substance. I see uric acid every day in the field (even more than Lou Sorkin) and know its not even a close second to what is left behind from bed bugs.

    Ok. I think I crossed the line and I apologize. But I and my wife really appreciate all the help the experts and the non-experts are providing in here. Thank you.

    Sorry, I missed this thread. Here's a link to large sized image to demonstrate.

    And also a female with some of the uric acid deposition plus fecal drop for comparison.
