How do I use Mothballs?

Follow the directions printed on the package. Mothballs are used to protect clothing made of natural fibres like wool from moth larvae. The appropriate amount of mothballs is placed in a sealable container. We suggest placing the mothballs in an old sock or a cloth bag to allow them to evaporate and to avoid direct contact with synthetic parts of clothing, – especially rayon and spandex – plastic buttons, zippers or fasteners because direct contact could damage these plastic parts. Mothballs are ineffective when used in an everyday closet because it will not allow naphthalene vapours to buildup.

Mothballs are an attractive hazard to children and may be harmful if swallowed. Always keep Mothballs out of reach of children and pets at all times.

Haemolytic anemia may occur following ingestion or sufficient exposure to naphthalene. Infants are at a greater risk of developing haemolytic anemia following exposure.
