How can you see bedbugs?

How can you see bedbugs? - briefly

Examine mattress seams, box‑spring folds, and bedding under a bright light, looking for tiny, reddish‑brown, oval insects about 4–5 mm long. A magnifying lens helps spot their dark bodies and pale eggs.

How can you see bedbugs? - in detail

Detecting bedbugs requires systematic visual inspection. Begin by removing bedding and examining the mattress seams, folds, and tags. Use a bright LED flashlight to illuminate dark crevices; a magnifying glass (10‑20×) reveals the tiny insects, which measure 4–5 mm in length and have a flattened, oval shape. Look for live specimens, which are reddish‑brown before feeding and become whitish after blood intake.

Identify indirect evidence as well:

  • Small dark spots (fecal stains) on sheets or walls.
  • Tiny, translucent exuviae shed after molting.
  • Rust‑colored spots (ingested blood) on mattress fabric.
  • Presence of eggs, about 1 mm, clustered in seams or behind headboards.

Conduct the inspection at night or in a dimly lit room, as bedbugs are more active after dark and may retreat when illuminated. Scan the following locations:

  1. Mattress edges, especially around the box spring.
  2. Bed frame joints, headboard, and footboard.
  3. Upholstered furniture seams and cushions.
  4. Baseboard cracks, electrical outlet covers, and wall hangings.
  5. Luggage racks, suitcase seams, and travel bags after trips.

If handheld tools are unavailable, a piece of clear tape pressed against suspected areas can capture specimens for later examination under a smartphone camera. For thoroughness, repeat the survey weekly for at least two months, as eggs hatch in 5–10 days and adult activity may be intermittent.
