Chemical solutions for pest control are not generally recommended. By the nature of their composition and application, many chemicals that might deter pests will also stain or break down fibers.
Most chemicals designed for moth control are unhealthy for humans to contact.
Freezing infested clothing is an option. In some cases, the best method of stabilization is dry-cleaning by a reputable company that works regularly with vintage fabrics. It should be noted that while dry-cleaning can kill a moth infestation, it does not act as a deterrent if the piece is later stored in a susceptible environment. Textiles to be stored should not come into contact with rubber bands, rubber cement or other adhesives, or self-adhesive labels, since these will break down over time, discoloring the surface of the stored piece. Packing materials such as bubble wrap, rubber, polyurethane foam rubber, and newspaper will also react negatively with stored textiles over time.
