How do silverfish primarily sustain themselves?

Silverfish primarily sustain themselves by consuming starches and paper products. These pests are known for their affinity for materials that contain carbohydrates, especially those rich in starch. This includes items such as paper, bookbinding, wallpaper, and even some types of fabric. Their feeding habits are primarily driven by the need for these organic compounds, which they rely on for energy and sustenance.

Silverfish have a unique digestive system that allows them to break down these complex carbohydrates, making them particularly suited to thrive in environments where these materials are present. This dietary preference not only influences where they are commonly found, such as in libraries, storage rooms, and attics, but also helps in understanding how to effectively manage and control silverfish infestations in various settings.
