In short, if it doesn’t smudge, then it is probably not from a bed bug. Additionally, just be aware that many other types of suspicious marks may smear as well, but they still may not be bed bug fecal matter. Smear Test – Firstly, this test is good to let you know that the spot you saw is NOT from a bed bug.Photos – Take some clear zoomed-in photos of your suspected fecal matter and email them to a bed bug specialist or entomologist in your area.The bed bug droppings are NOT something you can pick up and collect into a bag. Consistency – Does your spot smear when you wipe it with a wet cloth or Q-tip? Moreover, bed bug droppings do not flake off.The same way a Sharpie marker would look when you touch it to the fabric. If it seeps into cloth, then it will make the same crosshair type of lines on the side of where it is soaked in. Shape – Fecal matter will be circular if it does not bleed into the fabric.Typically bed bugs eat, sleep, have sex, and poop all around the host.
You will not find bed bug droppings across the apartment in the kitchen away from the bed unless you have many bed bugs roaming your place.
