Bed Bug

Human dwellings; typically found in mattresses, box springs, bed frames, furniture crevices, behind wallpaper, and under carpet edges.

Hematophagous (feeds exclusively on blood), preferring humans but will feed on other warm-blooded animals.

Nocturnal and cryptic; attracted to carbon dioxide and body heat; hide in tight clusters during the day; leave rusty dark spots (fecal matter) on bedding.

Risks: Bites result in itchy, red welts and can cause secondary skin infections, severe allergic reactions, anxiety, and insomnia. They are not confirmed vectors of disease but are difficult to eradicate.
