💡 Everyday Comparisons for Size, Mass & Speed

💡 The adult size of 5–6 mm is compared by the Korea Disease Control and Prevention Agency to an apple seed.
💡 Because it hides in bed or mattress crevices and bites while people sleep, it causes itching; there is no record of it transmitting disease, but scratching can lead to secondary skin infections (Korea Disease Control and Prevention Agency).

Reference standards: coach bus ~12 m, mid-size car ~4.9 m, compact car ~1 t, basketball hoop 3.05 m, credit card 8.56 cm.

📖 1. Overview

The bed bug is a small insect that sucks human blood, hiding in crevices during the day and coming out at night to bite people.

🦴 2. Anatomy & Morphology

The adult is a flat, dark brown oval about 5–6 mm long and wingless. It undergoes incomplete metamorphosis, passing from egg through 5 nymph stages to reach adulthood.

🔍 3. Ecology & Behavior

It hides in cracks of furniture or bedroom walls during the day and feeds on blood at night, especially before dawn. Both males and females feed once or twice a week, and females lay 2–5 eggs per day at intervals of 2–3 days, totaling about 200 eggs over a lifetime.

🇰🇷 4. Connection to Korea

The Korea Disease Control and Prevention Agency's bed bug information booklet states that 2 species, the bed bug and Bannalgae-bindae (a Korean animal name), are known to be distributed in Korea.
