There are two different cloth moth species to be concerned about as a home pest. The first is the webbing version of this moth, which is very common throughout the United States and can be found in many closets. The second is the casemaking version of this pest. Both moths are of the same size, but the casemaking cloth moth has dark spots on its body.
Mothproofing and clothes moth control are two different things. Mothproofing implies preventive applications of an insecticide to avoid infestation. Clothes moth or carpet beetle control is the correction of an existing infestation. Mothproofing is often accomplished by a special treatment during the manufacture of woolen fabric or other susceptible items.
