Water Quality District - Hazardous Waste
What are they?
Mothballs are a distinctive smelling, volatile solid, primarily used to repel moths. Mothballs contain chemicals designed to control pests and can be poisonous to pets, livestock, wildlife, and humans.
What Makes it Hazardous?
Mothballs contain either naphthalene or 1,4-dichlorobenzene. Both of these ingredients can produce harmful effects when inhaled. They are also poisonous if eaten. Dressing infants in clothing, or wrapping in blankets that were stored with naphthalene mothballs can cause poisoning.
- Avoid prolonged breathing of vapors.
- Keep away from children and pets. Mothballs may look like candy to a child.
- To protect clothing without using mothballs: clean according to manufacturer's instructions and store in airtight containers.
- Mothballs contain hazardous materials, and should not be placed in the trash.
- Annual Household Hazardous Waste Collection Event: Mothballs are accepted for disposal at Haz Waste Days , in September.
