What Are Bed Bugs and How Can You Recognize Them on a Mattress?

Bed bugs are small, nocturnal insects that feed on the blood of humans and animals. They are typically reddish-brown and are most commonly found in and around bedding, including mattresses.

Key points to recognize bed bugs on a mattress include:

Appearance of bed bugs
Signs of bites
Presence of shed skins
Dark spots on bedding
Unpleasant odor

Recognizing bed bugs effectively requires understanding their characteristics and the signs of their presence.

Appearance of Bed Bugs: Bed bugs are oval-shaped, flat, and about the size of an apple seed, usually measuring 4-5 mm. They have a reddish-brown color after feeding and a lighter hue when unfed. According to the University of Kentucky Entomology Department, bed bugs can be identified by their dark, beady eyes and six legs.
Signs of Bites: Bed bug bites often appear as small, red welts on the skin. They can occur in a line or cluster and are typically itchy. The Centers for Disease Control and Prevention (CDC) states that individuals react differently to bites, with some experiencing no symptoms at all. It is crucial to differentiate these bites from those of other common insects.
Presence of Shed Skins: Bed bugs undergo several molts as they mature, leaving behind tiny, exoskeleton-like skins. These discarded skins are usually found in areas where bed bugs reside, including the seams of mattresses and box springs. The website BedBug.com notes that discovering these skins is a strong indicator of an infestation.
Dark Spots on Bedding: Bed bugs excrete digested blood, which can leave dark stains on sheets and mattresses. These spots can appear as small, dark dots. The presence of these stains is often a telltale sign of bed bugs. Research by the University of Minnesota emphasizes finding these spots as a critical clue to detect an infestation.
Unpleasant Odor: Infestations of bed bugs can produce a musty, sweet odor due to the pheromones they release. This odor is often described as similar to that of overripe raspberries. According to the National Pest Management Association, this scent can alert residents to the presence of an infestation even in the absence of visible signs.

Recognizing these signs can help in identifying a possible bed bug problem, allowing for timely action to address the infestation.

What Do Bed Bugs Look Like in Close-Up Photos on Mattresses?

Bed bugs appear as small, reddish-brown insects about the size of an apple seed, with a flattened and oval shape. Close-up photos highlight their distinct features, such as tiny legs and antennae.
