Bed Bug

Found globally in human dwellings, typically hiding in mattress seams, bed frames, cracks, and crevices near sleeping areas.

Obligate hematophagous (blood-eaters), primarily feeding on human blood, though they may bite other mammals or birds.

Nocturnal insects that emerge at night to feed. They undergo incomplete metamorphosis (egg, nymph, adult) and can survive for several months without a blood meal.

Risks include itchy allergic reactions, skin rashes, psychological distress, and insomnia; though they carry pathogens, they are not known to transmit diseases to humans. There are no ecological benefits to humans.
