What does a bed bug look like: male and female, photos, size, how to get rid of it? - briefly
Adult bed bugs are flat, oval, reddish‑brown insects about 4–5 mm long; males and females appear identical, though females are marginally larger and develop a swollen abdomen after feeding. Effective control requires laundering bedding at ≥60 °C, vacuuming cracks and crevices, and applying a professional‑grade insecticide or heat treatment to the infested space.

Bed bugs are small, oval‑shaped insects that resemble tiny apples. Adults measure 4–5 mm in length, about the size of a grain of rice, and expand to roughly 7 mm after feeding. Their color ranges from light brown to reddish‑brown; after a blood meal they become markedly darker. The body is flat when unfed and becomes rounded when engorged.
Males and females appear virtually identical to the naked eye. Differentiation requires microscopic examination of the abdomen: females possess a larger, more rounded abdomen to accommodate eggs, while males have a slightly narrower abdomen and a visible copulatory organ at the rear. Both sexes have six legs, two antennae, and wingless thoraxes.
Key visual markers include:
- A smooth, elongated body without protruding legs.
- No wings or halteres.
- Tiny, dark eyes positioned near the antennae.
- A distinct “c‑shaped” or “U‑shaped” bite mark on the skin, often appearing in linear clusters.
Effective elimination combines chemical, physical, and preventive actions:
- Inspection – Examine seams, mattress tags, headboards, and cracks with a flashlight and magnifier.
- Isolation – Encase mattresses and box springs in zippered protective covers rated for bed‑bug containment; keep covers on for at least one year.
- Heat treatment – Raise ambient temperature of infested items to 50 °C (122 °F) for a minimum of 30 minutes; professional steamers reach 60–70 °C, killing all life stages.
- Cold exposure – Freeze items at –18 °C (0 °F) for at least four days; useful for clothing and small objects.
- Insecticide application – Use EPA‑registered residual sprays, dusts, or aerosols targeting cracks and crevices; rotate active ingredients to prevent resistance.
- Vacuuming – Remove live insects and eggs from surfaces; immediately dispose of bag contents in sealed plastic bags.
- Professional extermination – Engage licensed pest‑control operators for integrated pest‑management programs that may include fumigation or specialized desiccant powders.
Regular monitoring with interceptor traps placed under bed legs can confirm eradication progress. Maintaining a clutter‑free environment and washing bedding at high temperatures weekly reduces the likelihood of reinfestation.
