Bed Bug

Natural Habitat

Indoor environments, particularly dwelling areas like bedrooms, hotels, and public transportation, hiding in cracks, crevices, and mattresses.

Diet & Feeding

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

Behavior Patterns

Mainly nocturnal; they emerge at night to feed and hide during the day. They progress through five nymphal stages, requiring a blood meal to molt between each stage.

Risks & Benefits

Risks include allergic reactions to bites, skin rashes, and psychological distress (anxiety/insomnia). They are not known to transmit diseases to humans but are considered a significant public health pest. No known ecosystem benefits in human environments.
