The answer to 'what attracts silverfish' is that silverfish are attracted to warm, damp environments with high humidity and access to carbohydrates and cellulose-based materials. Silverfish thrive in areas with plenty of food sources like paper, books, clothing, and even glue and wallpaper. They are also drawn to places with high moisture levels like bathrooms, basements, and kitchens.
Silverfish are nocturnal pests that can be difficult to spot since they hide in cracks and crevices during the day. Signs of a silverfish infestation include seeing the insects themselves, finding shed exoskeletons, or noticing damage to paper goods, fabrics, and other household items.
