Bed Bug

Primarily human dwellings, hiding in mattress seams, bed frames, cracks, and crevices near sleeping areas.

Obligate hematophagy (blood-feeding), primarily on humans but also other warm-blooded animals.

Nocturnal parasites that emerge at night to feed. They undergo incomplete metamorphosis (egg, nymph, adult) and can survive months without a meal.

Potential risk includes itchy welts and allergic reactions from bites, as well as insomnia and psychological distress; they are not known vectors of disease but are a significant household pest.
