Are Naphthalene Balls Safe? Risks for Kids, Pets and Indoor Air

Mothballs are widely used, but they have real safety concerns.

The short answer

Naphthalene balls release fumes that can irritate eyes, nose and lungs, cause headaches and nausea, and are toxic if swallowed, especially for children and pets. They can also cause a blood problem in people with G6PD deficiency. Keep them out of reach, avoid using them in living spaces, and prefer clean storage, airtight containers and professional advice. This is general information, not medical advice.
