Bed Bug

Indoor environments, specifically in furniture, mattresses, bed frames, and wall crevices where humans sleep.

Obligate hematophages, primarily feeding on human blood, but will bite other warm-blooded animals if humans are unavailable.

Nocturnal parasites that hide during the day. They go through five nymph stages, requiring a blood meal to molt and mature.

Risks include itchy welts, allergic reactions, and secondary skin infections from scratching. They are significant pests that cause psychological distress and a financial burden to eradicate.
