How do you avoid bugs eating woolen jumpers?

To avoid bugs eating woolen jumpers, store them in airtight containers or bags to prevent moths and other pests from accessing them. You can also use natural repellents like cedar chips or lavender sachets, which deter insects. Regularly cleaning and vacuuming storage areas can help eliminate any potential eggs or larvae. Additionally, ensure that the jumpers are clean before storing, as food residue can attract pests.
