Naphthalene is an aromatic hydrocarbon found in coal car or crude oil. Naphthalene is used in the manufacture of plastics, resins, fuels, and dyes. It is also used as a fumigant insecticide that works by turning directly from a solid into a toxic vapor. This process is called sublimation. Most products containing naphthalene in the U.S. are used to control clothes moths in airtight containers.
