Bed Bug

Human dwellings, specifically inhabiting cracks and crevices, mattress seams, bed frames, and upholstered furniture.

Obligate hematophagous (blood-eaters), primarily feeding on human blood, though they may feed on other mammals or birds.

Nocturnal; they emerge from hiding at night to feed. They undergo incomplete metamorphosis (egg, nymph, adult) and require a blood meal to progress through each growth stage.

Risks include itchy allergic reactions to bites, skin infections from scratching, and significant psychological distress/insomnia. They are not known to transmit diseases to humans. There are no ecological benefits to humans.
