You just got out your winter wool clothes and blankets because the cold winter weather came along and there was a moth hole, furrow, or threadbare spot. Clothes moths!!! The moths lay eggs on wool or wool blends; the eggs hatch, and the worms (larvae) from the eggs eat the wool. Clothes moths hide in dark places where woollens are stored. Clothes moths also are reported to enjoy fur, hair, silk, and feathers (pillows). The white, full-grown worm (caterpillar) is about a half-inch long, as are the adult moths. The adults fly in a “fluttery” manner. The moths you see in the kitchen flying in a steadier path are probably pantry moths, which do not eat wool.

Dry ice, in combination with heavy plastic "contractor" trash bags, can kill moths, eggs, and larvae by fumigation, without putting harmful chemicals into your home environment. Place woollens and silks you want to fumigate in the heavy (“3-mil” or thicker) plastic bag. Use at least two pounds of dry ice per 114lt or 169lt bag. Using heavy leather or insulated gloves, wrap the dry ice in a large rag or old T-shirt. Place the dry ice inside the bag with the clothes, blankets, pillows, or upholstery to be fumigated. Tie the bag loosely with a twist tie. Seal the bag just loosely enough that the carbon dioxide gas can escape while the dry ice sublimates in the bag. You want the bag to fill with the carbon dioxide gas but not build up pressure.

The carbon dioxide gas from the dry ice displaces oxygen and kills - suffocates - whatever clothes moth eggs, larvae, and adults are in the bag. When the dry ice has completely sublimated, seal the bag tightly and store the bagged items. Clothes moth larvae that have just hatched are very tiny and can crawl into the bag from the outside through very small openings searching for wool “food”, so tight sealing of the storage bag after fumigation is important.
