How does a dangerous bedbug look? - briefly

The hazardous Cimex species presents a compact, oval silhouette measuring approximately 4–5 mm in length when unfed. The dorsal surface exhibits a smooth, glossy cuticle of deep reddish‑brown hue that darkens to a mahogany tone after a blood meal. Six short, sturdy legs emerge from the ventral side, each ending in a pair of claws that enable rapid clinging to fabric fibers. Two slender, segmented antennae extend forward, equipped with sensory receptors for heat and carbon dioxide.
Key morphological markers include:
- A distinct, triangular pronotum covering the head, giving the insect a shield‑like appearance.
- Compound eyes reduced to small ocelli, positioned laterally on the head.
- Mouthparts formed into a slender, elongated proboscis capable of piercing skin and extracting blood.
- Nymphal stages retain the same body outline but appear lighter in color and lack the fully developed pronotal shield.
After feeding, the abdomen expands noticeably, becoming rounded and more translucent, revealing a faint, whitish interior. The exoskeleton remains pliable, allowing the insect to flatten its body for concealment within mattress seams, upholstery, and crevices. These visual cues distinguish the dangerous variant from other household arthropods and facilitate early identification.
