What are the visual signs of bed bug activity?
Here are some pictures showing the visual signs of bed bug activity. The easiest way to confirm a bed bug infestation is to find some visual signs of bed bug activity. This could include blood spots or fecal streaks on sheets, pillows or furniture, or shed skins in cracks and crevices in the room. The ability to detect low-level bed bug activity is key in accomplishing early detection. The longer a bed bug infestation goes undetected, the more difficult and costly it becomes to eliminate them.
