Bed Bug

Tightly enclosed spaces near where people sleep, such as mattress seams, bed frames, cracks and crevices in furniture, or behind baseboards.

Obligate hematophages; they feed exclusively on the blood of humans and other warm-blooded animals.

Nocturnal pests that are most active at night; they undergo hemimetabolous metamorphosis including five nymphal stages that each require a blood meal to molt.

Risks include itchy skin welts, allergic reactions, secondary skin infections from scratching, and significant psychological distress; they are not known to transmit diseases to humans.
