There's nothing worse than opening your closet at the end of summer to find dozens of small holes all over your favourite sweater. If you plan on storing wool sweaters over the summer, you need to take special precautions to avoid moths. There are more than 11,000 different species of moths in North America, but luckily, there are only a few who covet your wool clothing. Of these, it's only the larva, not the adult moths, that do the damage. By properly storing your clothing, you can preserve your favourite new wool sweaters.
Have your wool sweaters cleaned before putting them up for the winter. Moths like to nest in the presence of organic materials. Body sweat and skin residue attract moths to your clothing.
Disturb your wool sweaters on a monthly basis. Pull your sweaters out of storage and shake them out. This helps you detect moths and disrupts the environment in which your sweaters are stored, making moths less likely to stick around.
Store your wool sweaters in special plastic storage bags. These bags are designed to protect your sweaters from moths without resorting to moth balls or regularly shakings. Once they are packed in these plastic containers, your sweaters can be left unattended until you're ready to wear them again.
Use moth repellents. You can buy commercial moth repellents or you can make your own by placing lavender, cedar chips, geranium and pine needles into a cloth bag and storing the bag near you sweaters.
Turn on the lights. The kinds of moths that eat wool sweaters avoid light, so storing your clothing in a well-lit area (e.g., an attic with a window) will deter moths from living and breeding in your clothes.
