It can grow in shabby books, eat paper for food, and is a pest.

Paper literature is more likely to attract insect pests because the carrier itself has substances suitable for insect reproduction and growth, such as plant fibers, the paste used for binding, and the poor ventilation of the library, improper placement of books and periodicals, high temperature and humidity, poor hygiene, dust and other residues, etc.

The silverfish is sensitive to temperature and humidity, and the ambient temperature suitable for silverfish breeding is 16 30, and the relative humidity is 75% 95%. When the temperature and humidity are not suitable for the breeding of the fish, the silverfish will migrate to the environment with suitable temperature and humidity.
