4Smell
Like many other species, bed bugs give off an odor when they are disturbed. It can be described as musty or sweet like rotting raspberries. Also, the smell can result from fecal materials, which can be stinky. Many people describe it as the odor of an herb called coriander. Along with this sign, you can notice stained fabrics with black spots or dark streaks. These are the excrement of bed bugs. [4]
