Major Pests: The major insect pests that attack textile collections are carpet beetles, moths, cockroaches, silverfish and firebrats. Pests can destroy a valuable doll or costume in a very short time, so examine for signs of vermin frequently. Practice good housekeeping to safeguard your collection. Keep display and storage areas clean. Do not permit food in the display or storage areas. Always place bagged moth crystals in the tops of textile storage containers or cases. The active ingredient in the crystals is heavier than air, so they must be suspended from inside tops of cases or containers, rather than placed on the bottom. Wash hands often when handling stored dolls or accessories, and use gloves to protect yourself from unknown contaminants
