Bed Bug (First Instar Nymph)

Indoor environments, specifically in close proximity to human sleeping areas such as mattress seams, bed frames, and furniture crevices.

Obligate hematophages (blood-feeders), primarily feeding on human blood during the night.

Nocturnal and elusive; they hide in dark crevices during the day and are attracted to the carbon dioxide and warmth emitted by hosts at night. They undergo five nymphal stages, requiring a blood meal to molt into the next stage.

Risks include itchy allergic reactions to bites, sleep deprivation, and psychological distress. While not known to transmit diseases to humans, heavy infestations can cause secondary skin infections from scratching.
