How to Get Rid of Moths Damaging Sweaters

Storing clothes in cedar chests can help prevent moth damage.

Moths damage fiber in sweaters that you leave untouched for long periods, most frequently in the summer season. Female moths lay their eggs on sweaters, and when the eggs hatch, the larvae feed on the fibers. These larvae are what cause little holes to appear. The majority of moth damage is usually in the armpit, front and lap areas. Sweaters that you have not laundered properly prior to storing are particularly prone to moth damage.

Instructions

1. Launder your sweaters properly before storing them away. Moths are attracted to clothes soiled with food, dirt or body odor.

2. Use cedar blocks or mothballs to prevent further moth damage. Cedar oil vapors only kill larvae, but mothballs kill all insects as they evaporate. You must use mothballs in an airtight space so the chemicals become concentrated enough to have an effect.

3. Seal your sweaters and clothes in a dry, airtight bag. Gallon-sized freezer bags are ideal.

Tips & Warnings

• Moth damage is most prevalent during the summer months. Humid regions are particularly prone to moth damage.

• Building your closet using cedar wood helps prevent moth damage.

• Mothballs contain chemicals harmful to humans and pets if ingested. Opt for cedar blocks to reduce any health risks.
