What do bedbugs look like and how can I get rid of them? - briefly

Bedbugs are tiny, oval, reddish‑brown insects roughly 4–5 mm in length that flatten when not feeding. Eradication requires laundering, vacuuming, and professional heat or insecticide treatment.

What do bedbugs look like and how can I get rid of them? - in detail

Bedbugs are tiny, oval insects measuring 4–5 mm in length when unfed and expanding to about 7 mm after a blood meal. Their bodies are flat, wingless, and covered with a reddish‑brown exoskeleton that may appear lighter after feeding. Six legs attach near the thorax, and the antennae are short and segmented. Adult females lay tiny, white eggs (0.5 mm) that are often glued to fabric seams or cracks.

Visible indicators include:

  • Small dark spots (fecal stains) on sheets, mattresses, or walls;
  • Tiny, translucent shells left after molting;
  • Live insects or freshly fed individuals, which may show a swollen, bright red abdomen;
  • Bite marks on skin, typically in clusters or linear patterns.

Effective eradication combines mechanical, thermal, and chemical actions:

  1. Inspection and isolation – Remove clutter, seal infested items in plastic bags, and dismantle bed frames to expose hidden crevices.
  2. Laundering – Wash bedding, clothing, and curtains in hot water (≥ 60 °C) and tumble dry on high heat for at least 30 minutes.
  3. Vacuuming – Use a HEPA‑rated vacuum on mattresses, box springs, furniture, and floor seams; discard the bag or seal the canister immediately.
  4. Encase mattresses – Install zippered, bedbug‑proof encasements on mattresses and box springs; keep them on for a minimum of one year.
  5. Heat treatment – Raise ambient temperature of rooms or infested objects to 50–55 °C for several hours; professional steamers can target cracks and seams.
  6. Cold treatment – Expose items to −18 °C for at least four days; suitable for small objects that cannot be heated.
  7. Chemical application – Apply EPA‑registered insecticides (pyrethroids, neonicotinoids, or desiccant dusts) according to label directions; repeat after 7–10 days to catch emerging nymphs.
  8. Professional intervention – Engage licensed pest‑management services for integrated approaches, including monitoring devices and follow‑up inspections.

Sustained vigilance—regularly checking seams, rotating bedding, and maintaining low‑clutter environments—prevents re‑infestation.
