Bed Bug

Found globally in human dwellings, particularly in cracks, crevices, mattress seams, bed frames, and upholstered furniture.

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

Nocturnal and elusive; they hide during the day and emerge at night to feed. They undergo incomplete metamorphosis (egg, nymph, adult) and require a blood meal to molt into each successive stage.

Risks: Causes itchy bites, allergic reactions, and significant psychological distress/insomnia. Although they carry pathogens, they are not known to transmit diseases to humans. Benefits: None to the human ecosystem; they are considered a significant domestic pest.
