Bed Bug

Natural Habitat

Human dwellings, specifically cracks and crevices near sleeping areas such as mattresses, box springs, bed frames, and headboards.

Diet & Feeding

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

Behavior Patterns

They are primarily nocturnal, hiding during the day and emerging at night to feed. They are attracted to the carbon dioxide and body heat emitted by hosts. Their life cycle involves five nymphal stages, each requiring a blood meal to molt.

Risks & Benefits

Risks include itchy skin rashes, psychological distress (anxiety/insomnia), and potential allergic reactions. While they are not known to transmit diseases, heavy infestations can lead to secondary skin infections from scratching. They provide no known ecological benefits in human environments.
