What do bedbugs and their traces look like? - briefly

Bedbugs are small, oval, reddish‑brown insects about 4–5 mm in length, with flat, wingless bodies. Their presence is confirmed by dark‑brown fecal spots, shed skins, and a faint sweet, musty odor.

What do bedbugs and their traces look like? - in detail

Bedbugs are small, oval‑shaped insects about 4–5 mm long, reddish‑brown in color, and flattened from top to bottom. Their bodies lack wings, and each adult possesses six legs, tiny antennae, and a pair of curved, needle‑like mouthparts used for piercing skin.

Visible signs of infestation include:

  • Live insects: active bugs found in seams of mattresses, box‑spring frames, headboards, and cracks in furniture.
  • Exuviae: translucent, pale skins shed after molting, often collected near hiding spots.
  • Fecal spots: dark, rust‑colored specks about the size of a pinhead, produced by digestion of blood; commonly located on bedding, walls, and mattress seams.
  • Blood stains: small, reddish marks on sheets or pillowcases, resulting from crushed bugs releasing ingested blood.
  • Odor: a sweet, musty scent similar to coriander, detectable in heavily infested areas.

Eggs are tiny (≈ 0.5 mm), white, and glued to fabric fibers or crevices; they hatch in 6–10 days. Nymphs resemble adults but are lighter in color and increase in size with each molt. A single female can lay 200–500 eggs over several months, leading to rapid population growth if unchecked.

Effective identification relies on inspecting mattress tags, box‑spring edges, and nearby furniture for the listed indicators. Early detection prevents widespread colonization and reduces the need for extensive remediation.
