Bed Bug

Human dwellings, specifically cracks and crevices near sleeping areas

Hematophagous; they feed exclusively on the blood of warm-blooded animals, primarily humans

Nocturnal activity, hiding during the day and emerging at night to feed; they undergo incomplete metamorphosis with five nymphal stages requiring blood meals to molt

Risks include physical reactions like itching and dermatitis, psychological distress, and potential allergic reactions; they are not known vectors of disease, but infestations can be difficult and costly to eradicate
