How to recognize bedbugs in a sofa? - briefly
Inspect seams, cushions, and fabric for tiny, reddish‑brown, oval insects about 4–5 mm long, as well as their white eggs and dark spots of digested blood. Use a flashlight and a fine‑toothed comb to examine hidden folds and the underside of the sofa.
How to recognize bedbugs in a sofa? - in detail
Bed bugs leave distinct visual and tactile clues on upholstered seating. Examine the fabric and cushions closely for the following indicators:
- Live insects: Small, oval-shaped bodies about 4‑5 mm long, reddish‑brown, flattened from top to bottom. When disturbed, they may appear darker due to blood intake.
- Molted skins: Transparent to light‑brown exoskeletons shed as the insects grow. These are typically found near seams, folds, or the underside of cushions.
- Fecal spots: Dark, pepper‑like specks measuring 0.5‑1 mm. They accumulate where the bugs feed, often along the edges of cushions, armrests, or the sofa frame.
- Blood stains: Tiny reddish or rust‑colored spots on the fabric, resulting from crushed bugs or minor feeding leaks. Stains may appear as smears after washing or cleaning.
- Odor: A sweet, musty scent resembling coriander, emitted by large colonies. The smell becomes noticeable in enclosed spaces or after prolonged infestation.
Inspect the sofa methodically:
- Remove all removable cushions and flip them to access the interior.
- Use a bright flashlight or a magnifying lens to enhance visibility of tiny specimens and shed skins.
- Run a gloved hand along seams, stitching, and the underside of the frame; a slight prickling sensation can indicate hidden bugs.
- Check the legs, base, and any attached wooden or metal supports, as these areas often serve as harborage.
- Place a piece of white paper beneath the sofa for several hours; any dropped fecal spots or dead insects will be evident.
If any of the above signs are present, collect a sample in a sealed container for laboratory confirmation. Immediate treatment—such as professional heat‑based extermination or approved insecticide application—should follow to prevent spread to other furniture or bedding.
