Bed Bug

Found globally in human dwellings, typically nesting in mattress seams, bed frames, furniture, and wall crevices near sleeping areas.

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

Nocturnal and elusive; they emerge from hiding at night to feed. They undergo incomplete metamorphosis (egg, nymph, adult) and require a blood meal to progress through each growth stage.

Risks include itchy skin welts, allergic reactions, secondary skin infections from scratching, and psychological distress/insomnia. They are not known to transmit diseases to humans. There are no ecological benefits to humans.
