Bed Bug (Exuviae/Casing)

Natural Habitat

Commonly found in human dwellings, specifically in cracks and crevices near sleeping areas such as mattresses, bed frames, and baseboards.

Diet & Feeding

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

Behavior Patterns

They are nocturnal, emerging at night to feed. They undergo incomplete metamorphosis (egg, nymph, adult) and must shed their exoskeleton (molt) to grow into the next stage.

Risks & Benefits

Risks include itchy skin rashes, psychological distress, and allergic reactions. They are not known to transmit diseases to humans but are considered a significant public health pest. There are no ecological benefits to their presence in human homes.
