How can I recognize that bedbugs have appeared in a couch? - briefly

How can I recognize that bedbugs have appeared in a couch? - in detail
Bed bugs leave distinct signs that can be detected on upholstered furniture. Visual inspection should focus on the following elements.
- Small, reddish‑brown insects measuring 4–5 mm, resembling apple seeds, often clustered near seams, cushions, and the underside of the frame.
- Dark, rust‑colored spots representing digested blood, typically found on fabric, wooden ribs, or nearby walls.
- Tiny, translucent exuviae (shed skins) that appear as pale shells after the insects molt; these are commonly located in creases and piping.
- Tiny white or yellowish eggs, about 0.5 mm in size, attached to fabric fibers or hidden in folds.
- Presence of live insects or nymphs when the couch is gently lifted or shaken, causing them to scatter.
Additional indicators include a faint, sweet, musty odor that intensifies with larger populations, and occasional bite marks on nearby occupants, characterized by itchy, red welts.
To confirm an infestation, collect suspected specimens—adults, nymphs, shells, or eggs—and examine them under magnification. Comparison with verified images of Cimex lectularius confirms identification. If uncertainty remains, professional pest‑control services can perform laboratory analysis of collected samples.
Preventive measures involve regularly vacuuming all surfaces, inspecting seams and stitching after travel or purchase, and encasing the couch in a bed‑bug‑proof cover that eliminates hiding places. Prompt detection and targeted treatment reduce the risk of spread to other furniture or bedding.
