Gainda Naphthalene Balls are small, round balls made from naphthalene, a chemical compound commonly used to repel insects, especially moths, and to prevent unpleasant odors in enclosed spaces. These balls are typically used in wardrobes, drawers, and storage areas to keep clothes fresh and protected from moths and other pests. Naphthalene has a strong, distinctive odor that helps deter insects. Gainda is a popular brand offering these balls, which are known for their effectiveness in maintaining hygiene and preventing foul smells. However, it’s important to use them in well-ventilated areas, as prolonged exposure to naphthalene fumes can be harmful.
