What Are Naphthalene Balls?
Naphthalene balls, also known as mothballs, are small, white, crystalline balls made primarily of naphthalene or paradichlorobenzene. They are commonly used as insect repellents, particularly against moths, cockroaches, and other pests.
Uses of Naphthalene Balls
Pest Control – Placed in wardrobes, storage boxes, and drawers to repel moths and insects.
Odor Removal – Used in toilets, shoe racks, and damp areas to absorb bad odors.
Preservation – Helps prevent mold growth in stored fabrics, books, and wooden furniture.
Industrial Use – Used in some chemical processes and as a raw material in dye and resin production.
How Do They Work?
Naphthalene balls sublimate, meaning they slowly change from solid to gas without becoming liquid. The vapor they release is toxic to insects, preventing infestations.
Health & Safety Concerns
Toxic to Humans & Pets – Can cause nausea, headaches, and dizziness if inhaled in high amounts.
Flammable – Should be stored away from heat sources.
Environmental Hazard – Some types are banned or restricted in various countries due to potential groundwater contamination.
Alternatives
Due to health risks, natural alternatives like cedarwood, dried lavender, or neem leaves are often recommended for moth and pest control.
