Unlike the moths that fly toward your porch lights, Clothes Moths (the Casemaking and Webbing varieties) are secretive, hate the light, and can destroy a wool wardrobe before you ever see a single adult moth.
The AdultVery small (about 1/4 inch), buff or golden-colored moths. They do not have the "dusty" scales of common outdoor moths.
The BehaviorIf you see a small moth fluttering in a dark closet or running across a wool rug, it is likely a clothes moth. They are poor fliers and prefer to scuttle or hop.
The LarvaeSmall, white caterpillars that often live inside a "case" made of the fibers they are eating.
DietThey only eat animal-based fibers. This includes wool, silk, fur, feathers, and leather. They will not eat synthetic fabrics like polyester unless they are blended with wool.
Darkness LoversThey are almost never seen in well-lit areas. They hide in the deepest corners of closets, under heavy furniture, or inside the folds of stored blankets.
The "Hole" TruthThey don't just eat one spot; they tend to graze, leaving scattered, irregular holes throughout a garment.
I see moths flying around my pantry—are those clothes moths?Usually, no. Those are likely Indian Meal Moths. Clothes moths are smaller, lighter in color, and stay away from the kitchen and toward the closet.
Do cedar blocks actually work?Cedar can repel moths, but it doesn't kill existing larvae or eggs. If you already have an infestation, cedar won't solve the problem.
How do I save my wool sweaters?The best defense is "Heat or Cold." Dry cleaning kills larvae, as does putting a garment in a sealed bag in the freezer for 72 hours.
