Bed Bug (Nymph)

Natural Habitat

Found in human dwellings, typically in cracks and crevices, bed frames, mattresses, and behind wallpaper. They prefer areas where people sleep or spend long periods.

Diet & Feeding

Obligate hematophagous (blood-feeders). They feed almost exclusively on human blood but may also feed on other warm-blooded animals if humans are unavailable.

Behavior Patterns

Nocturnal and elusive. They emerge from hiding once every 5-10 days to feed, attracted by body heat and CO2. Life cycle includes five nymphal stages, each requiring a blood meal to molt.

Risks & Benefits

Risks include itchy skin rashes, psychological distress, and allergic reactions. While they are not known to transmit diseases to humans, infestations are difficult and expensive to eradicate. There are no known ecosystem benefits for this species in human environments.
