I believe you're referring to "naphthalene balls." Naphthalene balls are solid white, volatile, and highly aromatic crystalline balls derived from naphthalene, a hydrocarbon compound obtained from coal tar. These balls are widely used as a household moth repellent due to their strong odor, which deters moths and other insects from infesting clothes, blankets, and other stored items.

Naphthalene balls sublimate, meaning they transition from a solid to a gas without passing through the liquid phase. As they sublimate, they release fumes that help in repelling insects. However, it's important to use them in well-ventilated areas as prolonged exposure to the fumes may be harmful, particularly in enclosed spaces.

They are commonly placed in closets, storage containers, or areas where clothes are kept to prevent damage caused by moth larvae. These balls slowly evaporate over time and need to be replaced periodically to maintain their effectiveness.

Despite their usefulness as a moth repellent, caution is advised while handling them, especially around children or pets, as ingestion or prolonged exposure can be toxic. It's recommended to read and follow the manufacturer's instructions and safety guidelines when using naphthalene balls.
