Some archival material is more susceptible to pests than others. Here are some materials found in archives to monitor for pest infestations:
- Paper often has gelatin based sizing (sizing is what makes paper slightly water repellant, smooth, and durable). This high protein gelatin sizing is nutritious for pests.
- Bound Material
- Leather, vellum, parchment, wood, rabbit skin glue, isinglass glue, and cloth are all found in bound material and targeted by pests, such as silverfish and mice, as sources of food.
- Leather, and the residual products left on leather from the tanning process and leather dressings, attract pests. There are sugars and salts present that attract beetles, rodents, and silverfish.
- Gelatin, and Albumen Photographs
- These photographic processes incorporate high-protein materials such as gelatin and egg whites, making them attractive to pests such as silverfish.
