Bed Bug

Natural Habitat

Found globally in human dwellings, typically nesting in cracks, crevices, mattress seams, and upholstered furniture.

Diet & Feeding

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

Behavior Patterns

Nocturnal and elusive; they hide during the day and emerge at night to feed. They undergo hemimetabolous metamorphosis, passing through five nymphal stages that each require a blood meal to molt.

Risks & Benefits

Risks include itchy allergic reactions to bites, skin rashes, and psychological distress/insomnia. No documented ecosystem benefits in human environments; they are considered a significant domestic pest.
