The answer to 'why is my silverfish damage' is that silverfish are small, wingless insects that feed on organic materials like paper, clothing, and food. They leave behind small holes, stains, and scales as they feed, which can cause damage to your home. Silverfish thrive in damp, dark areas and are often found in bathrooms, kitchens, and basements.
The most common signs of silverfish damage include small, irregularly-shaped holes in papers, books, and fabrics, as well as the presence of their shed exoskeletons. They can also contaminate food and leave behind a powdery residue from their fecal matter.
