What type of food do silverfish primarily consume?

Silverfish primarily consume items that are rich in carbohydrates and proteins, which explains why they are particularly attracted to books, paper, and glues. These materials contain starch, sugars, and other organic compounds that serve as an effective food source for silverfish. Their diet primarily revolves around these cellulose-rich substrates, which provide the necessary nutrients for their growth and reproduction.

The reason this choice is the most accurate is that it aligns perfectly with silverfish's known feeding behavior and their natural habitat, often found in dark, damp areas where such organic materials are prevalent. This specific diet also highlights why silverfish are often a nuisance in homes, especially in areas where paper products, books, and glues are stored.

While silverfish may occasionally feed on other organic materials, the selected answer reflects their primary consumption habits in a more specific and focused manner.
