Rodents in Libraries: A Serious Threat to Library Collections and Preservation

Libraries are important institutions that preserve knowledge, culture, education, and history. They store books, manuscripts, newspapers, journals, maps, archives, and digital resources for future generations. However, library collections are constantly threatened by environmental conditions, natural disasters, and biological pests. Among these pests, rodents are one of the most dangerous and destructive enemies of libraries.

Rodents such as rats and mice can seriously damage books, shelves, furniture, electrical systems, and even library buildings. They chew paper materials, destroy bindings, contaminate collections, and create unhealthy environments. If rodent infestations are not controlled quickly, libraries may suffer major financial and cultural losses.

In library science, rodent control is an essential part of preservation and conservation management. Protecting collections from rodents helps maintain the quality, safety, and lifespan of valuable materials.

This article explains the impact of rodents in libraries, the damage they cause, prevention techniques, pest management methods, and the role of librarians in protecting collections.

What Are Rodents?

Rodents are mammals belonging to the order Rodentia. They are characterized by continuously growing front teeth that they use for gnawing and chewing.

Common Features of Rodents
