Bed Bug (Nymph)

Indoor environments, primarily in cracks and crevices near sleeping areas such as mattress seams, bed frames, and furniture.

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

Nocturnal and elusive. They undergo five nymphal stages (instars) and must have a blood meal to molt into the next stage. They are attracted to heat and carbon dioxide.

Risks include itchy skin rashes, psychological distress, and allergic reactions. They are not known to transmit diseases to humans. There are no ecological benefits in a domestic setting; they are considered significant household pests.
