Bed Bug

Natural Habitat

Primarily found in human dwellings, especially beds, mattresses, bed frames, and furniture where they can easily access sleeping hosts. They hide in cracks and crevices during the day.

Diet & Feeding

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

Behavior Patterns

Nocturnal feeders, emerging from their hiding spots to feed on resting hosts. They are attracted by carbon dioxide and body heat. They are skilled hiders and can be difficult to detect. Females lay eggs in secluded spots.

Risks & Benefits

Potential risks include itchy bites, allergic reactions (ranging from mild to severe), secondary skin infections from scratching, and psychological distress (anxiety, insomnia). They are not known to transmit diseases to humans. There are no known benefits of bed bugs to humans or the ecosystem.
