What materials do silverfish and firebrats usually damage?

Silverfish and firebrats are pests that are notorious for causing damage to a variety of materials. They feed on starch, which makes glue and certain types of paper susceptible to their activities. Their affinity for carbohydrates means they can also damage cellulose found in paper products, making them a common pest in places where books, magazines, or documents are stored.

In addition to starchy materials, silverfish and firebrats can also cause harm to leather and fur products. Since they are drawn to protein-based materials, any items made from animal products could potentially fall victim to their feeding habits.

Light clothing, especially those made from natural fibers or containing starch, is not safe from these pests either. They can create holes and other forms of damage in garments, particularly those left in dark, damp areas where silverfish and firebrats typically thrive.

Given their diverse feeding habits and the breadth of items they can damage, it is accurate to recognize that silverfish and firebrats can affect glue, leather, fur, paper, and light clothing. This comprehensive understanding of their destructive tendencies justifies selecting the option indicating that all the mentioned materials are at risk.
