How can a sofa be inspected for bedbugs at home? - in detail
Inspecting a couch for Cimex lectularius requires a systematic approach that covers all surfaces and hidden zones. Begin by removing any removable covers, cushions, and throws. Wash or seal them according to manufacturer instructions; this eliminates potential refuge areas and makes inspection easier.

Visual examination

Place the upholstery on a flat surface under bright lighting.
Look for live insects, which appear as flat, reddish‑brown bugs about 4‑5 mm long.
Identify shed exoskeletons (lighter, translucent shells) and eggs (tiny, white‑to‑cream specks) near seams, folds, and stitching.
Scan the underside of cushions, the frame, and any crevices where fabric meets wood or metal.

Tactile check

Run fingertips along seams, buttonholes, and tufted areas.
Feel for small, moving specks or a slight rust‑colored residue known as fecal stains.
Gently press the fabric; bedbugs may be dislodged and visible on the hand.

Use of tools

A magnifying glass (10‑20×) clarifies tiny eggs and nymphs.
A flashlight with a narrow beam highlights shadows in deep folds.
Sticky traps placed under the sofa legs for 24‑48 hours capture wandering specimens.

Isolation and containment

After inspection, seal removed covers in sealed plastic bags to prevent escape.
Vacuum the entire sofa, paying special attention to seams and joints; immediately discard the vacuum bag or clean the canister.

Documentation

Photograph any findings, noting location (e.g., “right armrest seam”) for targeted treatment.
Record the date and conditions (lighting, temperature) to track infestation progress.

If any life stage is confirmed, proceed with appropriate control measures such as heat treatment (raising temperature to ≥ 50 °C for several hours), professional pesticide application, or replacement of severely infested components. Regular re‑inspection every two weeks for a month ensures eradication.
