Bed Bug

Found globally in human dwellings, typically nesting in bedding, mattresses, bed frames, cracks, and crevices near sleeping areas.

Obligate hematophages; they feed exclusively on the blood of warm-blooded animals, primarily humans.

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

No known ecosystem benefits. Risks include allergic reactions to bites, secondary skin infections from scratching, psychological distress, and insomnia. They are not known to transmit diseases to humans.
