Bed Bug

Indoor environments, primarily in cracks and crevices near sleeping areas (mattress seams, bed frames, headboards, behind wallpaper).

Obligate hematophages; they feed exclusively on animal blood, primarily from humans, though they can feed on other warm-blooded animals.

Nocturnal and elusive; they emerge at night to feed and hide during the day. They have five nymphal stages requiring blood meals to molt and can live for several months without feeding.

Risks include physical reactions such as itchy welts, allergic reactions, and significant psychological distress (insomnia/anxiety). They are not known to transmit diseases to humans but are considered a major indoor pest infestation risk.
