Bed Bug (Instar/Egg stage)

Domestic environments, specifically beds, furniture, and cracks/crevices near sleeping areas.

Obligate blood feeders, primarily targeting humans during sleep.

Nocturnal, hiding during the day in tight spaces and emerging at night to feed. They undergo incomplete metamorphosis (egg, nymph instars, adult).

Significant urban pest. Risks include itchy allergic reactions to bites, skin infections from scratching, and psychological distress. They do not transmit diseases.
