Bed bug

Indoor environments, specifically in furniture, mattress seams, bed frames, and cracks or crevices near sleeping areas.

Obligate hematophagous (blood-eaters), primarily feeding on human blood.

Nocturnal pests that hide during the day and emerge at night to feed. They undergo incomplete metamorphosis with five nymphal stages, each requiring a blood meal to molt.

Significant household pest. Bites can cause itchy red welts, allergic reactions, and psychological distress. While they do not typically transmit diseases, they are difficult and expensive to eradicate.
