I have been inspecting my bedding after getting bites and haven’t seen anything in my climb-up interceptors but found these stains on the pillowcases and seams of the pillows this morning. I wanted to see if this looked to be from bed bugs…thank you. I had a professional inspection a week and a half ago which didn’t yield anything but didn’t have this type of evidence then.
Unfortunately it is hard to definitively say that this is evidence or is from bedbugs. It could be possible but unfortunately other things could potentially cause the stains as well, if you are not seeing any activity in your climb up and you have thoroughly steamed your bedframe, some other things to look into might be to see if your sheets have hanged off the side of the bed, if your headboard is touching the wall, or if there is another way bedbugs might be able to access your bed as if were bedbugs you should see some sort of activity or more signs of them.
