How to Protect Yourself from Wool Moths

HOW TO PROTECT YOUR GARMENTS FROM MOTHS

Anyone who loves wool or works with natural yarns knows that, sooner or later, an invisible but fearsome enemy arrives: moths. These small, seemingly harmless insects can damage sweaters, scarves, balls of yarn, and fine garments.

In this article, we'll discover what they attack, how they work, and, above all, how to protect your wool garments.

Moths don't affect all fabrics equally. They're attracted almost exclusively to animal fibers, such as:

• Wool

• Cashmere

• Alpaca

• Camel

• Mohair

• Raw silk

Plant fibers (cotton, linen, hemp) and synthetic fibers (acrylic, polyester, nylon) are not attacked, but be careful: if mixed with wool they can still become a refuge for larvae.

Warning: moths do not only feed on finished garments, but also on balls of natural yarn.

The larvae cause the damage. Here's what happens:

• The adult moth lays eggs on natural fabrics and yarns.

• The eggs hatch into voracious larvae that feed on keratin, a protein found in wool and animal hair.

• The larvae tunnel into the wool, creating holes, broken threads and sometimes irreversible damage.

• Once they have grown, they become new adult moths and the cycle begins again.

It all happens silently, often in dark, warm, and humid environments: closets, closed boxes, drawers, attics, etc.

• Prevention is the most effective weapon. Here are some good practices to protect wool and yarn:

  • Clean before storing: Wash items before storing them, even if they appear clean; sweat, skin, and perfumes attract moths. Balls of yarn should also be stored dry and clean, never damp or exposed to dust.

  • Smart storage: Use vacuum bags, airtight containers, or tightly closed cotton bags. Add bay leaves, lavender, cloves, cedar, or other natural repellents. Ventilate closets and boxes periodically.

  • Regular inspections: Check stored clothing and yarns occasionally. Expose them to sunlight: larvae hate light.

  What to do if you have moths

  If you find holes in your sweaters or signs of larvae in your balls of yarn, take action immediately:

  • Wash everything hot: if possible, wash your clothes at 60°C or take them to the dry cleaners. The larvae die from heat.

  • Clean closets: Vacuum and use white vinegar in corners, especially drawers and wooden furniture.

  • Use natural or chemical remedies: natural repellents (lavender or cedar essential oil) or specific moth-repellent products

  If you use natural yarns like wool or cashmere, especially if they're fine or expensive, store them carefully. Avoid leaving them exposed to the air for extended periods, especially in spring and summer, and never store used yarns without washing or checking them.
