Signs of bed bugs
Bed bug bites
For obvious reasons, bed bugs are one of the most common signs of a bed bug problem. They often appear in a line or cluster on the face, neck, arms, legs, and other exposed skin. And while not everyone reacts to bed bug bites, many people develop red, itchy welts.
Adult bed bugs & nymphs
Another clear indication is finding reddish-brown bugs. Adult bed bugs are about the size of an apple seed, and nymphs are similar in appearance, only smaller and more whitish yellow. Both are often found on mattresses, box springs, headboards, and other furniture in an infested space. Bed bugs are mostly active at night and hide during the day, but in the case of severe infestations, you may see them anytime of day.
Bed bug eggs
Bed bug eggs are tiny, measuring about 1 mm in size. They are usually translucent or pearly white. These eggs are typically found in clusters and are often attached to surfaces near the bugs' hiding spots.
Dark brown or reddish stains
Bed bugs leave behind fecal stains that appear as small, dark brown or reddish spots on bedding, mattresses, furniture, and walls. These stains are a result of the digested blood they excrete.
As they develop, bed bugs shed their exoskeletons. These discarded skins are light brown and can be found near their hiding places.
When an infestation of bed bugs is large, there may be an accompanying odor that is often described as musty and sweet.
