Cloves in the closet
As she passed by the office coat closet, my friend Jennifer commented on how coats smell like mothballs when they freshly come out of summer storage and how awful the smell is. Mothballs, used to protect clothes from damage by moths, are either made of naphthalene or paradichlorobenzene. Both chemicals kill moths and moth larvae with fumes by transitioning from solid to toxic gas. Taking clothes out after they have been sealed all summer in bags with mothballs can be harmful for people to breathe in, especially infants.
A natural alternative to mothballs I have always used is cloves! I put them loose (or they can also be made into sashes) inside folded sweaters and my stored clothes have never suffered any damage. Cloves are dried flower buds of the clove tree. They are well known for their medicinal benefits. I find the smell of cloves pleasant and it dissipates naturally.
