The answer to 'what attracts silverfish' is that silverfish are attracted to damp, humid environments and foods high in carbohydrates and starches. Silverfish thrive in areas with high moisture levels, such as bathrooms, kitchens, and basements, where they can find sources of food like paper, cardboard, and glue. They are also drawn to starch-based products like flour, cereal, and book bindings.
Silverfish are nocturnal insects that can be difficult to spot, as they hide in cracks and crevices during the day. Signs of a silverfish infestation may include seeing the insects themselves, as well as small holes or damage to paper products, fabrics, and other household items.
