Common Bed Bug (Nymph/Egg stage)

Indoor environments, specifically within cracks and crevices of furniture, mattresses, baseboards, and luggage in human dwellings.

Obligate hematophages; they feed exclusively on the blood of warm-blooded animals, primarily humans. Nymphs require a blood meal to molt to the next stage.

Nocturnal and elusive; they hide during the day and emerge at night to feed. They undergo incomplete metamorphosis (egg, five nymphal stages, and adult).

Risks include itchy skin welts, allergic reactions, and psychological distress/insomnia. They are not known to transmit diseases to humans but are significant household pests.
