Bed Bug

Indoor environments, primarily in cracks and crevices of beds, mattresses, and upholstered furniture in human dwellings.

Obligate hematophagous (blood-feeding) insects that primarily feed on human blood, usually at night.

Nocturnal and elusive; they 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.

They do not transmit diseases but their bites can cause skin rashes, allergic reactions, and psychological distress. They are considered a significant public health pest due to the difficulty and cost of eradication.
