Mothballs stink and only work in closed-off spaces. When possible, avoid using them entirely. If you are really worried about moths getting into your clothing, then focus on prevention. Don't store your clothes in an area that moths have access to. If your attic or storage area needs to be better sealed or screened for protection, now is a great time for that project. Note: Thorough drying and ironing will destroy moth eggs that may have gotten into clothing from other sources. Another good reason to always clean and dry clothes first! Plus: How to Control Bugs
