What type of food do Silverfish primarily feed on?

Silverfish primarily feed on substances that contain starch, such as paper, books, and other starchy materials. Their diet typically includes carbohydrates, which are found in many organic materials, including some types of wallpaper and glue. They are particularly known for damaging items that contain starch because they are attracted to these types of nutrients, which support their growth and reproduction.

While it’s true that Silverfish can consume a variety of materials, including those that may appeal to other options listed, their preference for starchy substances makes the focus on this aspect of their diet the most accurate. Additionally, silverfish can occasionally eat sugars, but their primary energy source stems from starches, setting it apart as the correct response in the context of their most common feeding habits.
