Clothes moth larvae harbor in and near animal fibers such as wool, mohair, leather, felt, cashmere, fur, and feathers. They can also feed on cotton, linen, silk, and in some cases, synthetic fibers. Moth larvae like dark, warm, and humid spaces as well as dirty clothing.
Infested items need to be removed and either thrown away or deep cleaned.
Clothing: dry cleaning is the most effective larvae removal method, otherwise items can be washed in a hot water cycle exceeding 120 degrees for a minimum of 20 minutes.
Vacuuming: vacuum all flooring paying special attention to dark corners and crevices. Remove and discard the vacuum contents immediately. If using a canister vacuum, wash in hot and soapy water.
Steam Cleaning: steam cleaning is one of the most effective methods for larvae removal. Steam clean floors and furniture if possible, paying special attention to seams and crevices.
Other areas to clean: wash walls, shelves, and other surfaces with hot (if possible) and soapy water.
Optional (not guaranteed) methods for larvae removal: Leaving items outside for sunlight and wind exposure can create an inhospitable environment for the larvae. Other items can be sealed in a plastic bag and placed in the freezer for at least three days to kill all life stages of the moth.
Prevention:
- Store clothing and other fibers in vacuum sealed storage bags or plastic storage totes with a tight fitting lid.
- Air out closets periodically and rotate clothing items often since these moths hate light and movement.
- Continue cleaning the home regularly.
