Bed Bug

Found globally in human dwellings, typically hiding in cracks, crevices, upholstery, mattresses, and bed frames during the day.

Obligate hematophages, meaning they feed exclusively on the blood of warm-blooded animals, primarily humans.

Nocturnal pests that follow carbon dioxide and heat to find hosts; they undergo hemimetabolous metamorphosis across five nymphal stages, requiring a blood meal to molt into the next stage.

While not known to transmit diseases, their bites can cause allergic reactions, skin rashes, and significant psychological distress or insomnia. They offer no ecological benefits in human environments and are considered a major domestic pest.
