The answer to 'why is my silverfish damage' is that silverfish are small, wingless insects that feed on starch, cellulose, and other carbohydrates, often causing damage to household items like books, wallpaper, and clothing. They are attracted to damp, dark environments and can leave behind unsightly trails and holes as they feed.
Silverfish infestations are common, especially in older homes or areas with high humidity. Signs of silverfish damage include small holes or irregular patterns in papers, fabrics, and other materials, as well as the presence of the insects themselves, which are typically silvery-gray in color and move quickly.
