Bed Bug (fecal spotting/dried blood)
Scientific Name: Cimex lectularius
Order & Family: Order: Hemiptera, Family: Cimicidae
Size: Adults are 4–5 mm long; nymph stages are smaller; the visual evidence in the photo represents a small spot typically 1-2 mm.
Natural Habitat
Human dwellings, specifically cracks and crevices near sleeping areas such as mattress seams, bed frames, and baseboards.
Diet & Feeding
Obligate hematophages, meaning they feed exclusively on the blood of warm-blooded animals, primarily humans.
Behavior Patterns
Nocturnal parasites that hide during the day and emerge at night to feed. They undergo incomplete metamorphosis (egg, nymph, adult) and require a blood meal to molt into the next stage.
Risks & Benefits
Risks include itchy allergic reactions to bites, secondary skin infections from scratching, and significant psychological distress/insomnia. They are not known to transmit diseases to humans but cause significant economic burden and infestation issues.
